Running BOINC as a daemon or system service
Make_BOINC_Service.sh is a command-line shell script to set up the BOINC Client to run as a daemon at system startup. It can be used with either full GUI installations (BOINC Manager) or the stand-alone BOINC Client. (If you don't use the boinc daemon that came with the GUI installation, you should check the /Library/LaunchDaemons/edu.berkeley.boinc file that the Make_BOINC_Service.sh script generates for double slashes (//) and remove them if necessary.)
When run as a daemon:
- The BOINC Client always runs even when no user is logged in. However, it still observes the Activity settings as set by the Manager or the boinc_cmd application (Run always, Run based on preferences, Suspend, Snooze; Network activity always available, Network activity based on preferences, Network activity suspended.)
- Quitting the BOINC Manager will not cause the Client to exit.
- Most projects have upgraded their graphics to version 6 and will display graphics properly on BOINC version 6.2 and later even when running as a daemon. However, older style (version 5) application graphics (including screen saver graphics) are not available when the Client runs as a daemon.
- The BOINC Client may not successfully detect the presence of a GPU, so BOINC Project applications may not be able to use the GPU.
- The following apply to the full GUI installation (BOINC Manager):
- You may need BOINC version 6.2 or later to work properly as a daemon.
- Normally, BOINC Manager starts up automatically when each user logs in. You can change this as explained below.
- If you wish to block some users from using BOINC Manager, move it out of the /Applications directory into a directory with restricted permissions. Due to the Manager's internal permissions, you can move it but cannot copy it. See Client security and sandboxing for more information.
Disabling auto-launch of BOINC Manager
By default, BOINC Manager starts up automatically when each user logs in. You can override this behavior by removing the BOINC Manager Login Item for selected users, either via the Accounts System Preferences panel or by creating a nologinitems.txt file in the BOINC Data folder. This should be a plain text file containing a list of users to be excluded from auto-launch, one user name per line.
An easy way to create this file is to type the following in terminal, then edit the file to remove unwanted entries:
After creating this file, run the installer. The installer will delete the Login Item for each user listed in the file. Entries which are not names of actual users are ignored (e.g., Shared, Deleted Users.)
Using BOINC's security features with the stand-alone BOINC Client
Beginning with version 5.5.4, the Macintosh BOINC Manager Installer implements additional security to protect your computer data from potential theft or accidental or malicious damage by limiting BOINC projects' access to your system and data, as described in Client security and sandboxing. We recommend that stand-alone BOINC Client installations also take advantage of this protection. You can do this by running the Mac_SA_Secure.sh command-line shell script after installing the stand-alone Client, and again any time you upgrade the Client.
Although we don't recommend it, you can remove these protections by running the Mac_SA_Insecure.sh script.
Moving BOINC Manager or BOINC Data Folder to a Different Drive
It is possible to run BOINC on the Mac with the BOINC Manager application or the BOINC Data folder on a drive other than the boot drive. This is complicated a bit by the need to set up the special permissions for BOINC's sandbox security, but it can be done. These instructions are provided with no warranty; use them at your own risk.
Here are instructions for moving both the application and the data (you can move either or both):
Shortcut: instead of typing a path in the Terminal application, you can drag a folder or file from a Finder window onto the Terminal window. If you do this, omit the quotation marks around the path!
[1] Quit BOINC.
[2] If you only want to move the BOINC Manager application, skip to step [4].
Copy the BOINC Data directory from the '/Library/Application Support/' directory to the desired drive. Rename the original BOINC Data directory or move it to a different directory on your boot drive as a backup safety measure. In any case, you must now not have a '/Library/Application Support/BOINC Data' directory before the next step.
[3] Create a symbolic link to the new BOINC Data directory in place of the old one. Enter the following in the Terminal application:
Substituting your new path for {newDataPath}; for example: '/Volumes/newDrive/myData'.
[4] If you only want to move the BOINC Data, skip to step [5].
Copy BOINCManager.app from '/Applications/BOINCManager.app' to the desired drive, and move the original into the trash. (The Finder may not show the filename extension '.app').
Create a symbolic link to the new copy in place of the old one. Enter the following in the Terminal application:
Substituting your new path for {newAppPath}; for example: '/Volumes/newDrive/myApps'
[5] IMPORTANT: you must create symbolic links. Macintosh aliases created with the Finder will not work!
Run the script Mac_SA_Secure.sh to set up proper permissions at the new locations. Enter the following in the Terminal application:
where {newDataPath} is as above and {path} is the path to the Mac_SA_Secure.sh script. (As before, you can drag the Mac_SA_Secure.sh file from a Finder window onto the Terminal window instead of typing its path.)
[6] Relaunch BOINC.
IMPORTANT: Each time you run the installer, you will need to repeat this. You may also need to repeat it after upgrading to a new version of Mac OSX. The installer will replace the symbolic link to the Manager with the new Manager, and will replace the symbolic link to the BOINC Data directory with a new initialized BOINC Data directory with no projects attached. You must:
- cancel out of the 'Attach to Project' dialog
- quit BOINC
- move that new initialized BOINC Data directory to the trash
- repeat steps [2] through [4].
Note: according to this discussion, the target drive must have 'Owners Enabled' set.
For safety, always make a backup copy of your BOINC Data before performing these steps.
Selecting which users may run BOINC Manager
Due to new restrictions imposed by OS 10.6 Snow Leopard, there has been a change in BOINC's security implementation. Non-administrative users can no longer run BOINC Manager unless they are added to group boinc_master.
As of BOINC 6.10.5, the BOINC installer asks whether or not you wish to add all non-admin users to group boinc_master. (As before, the installer automatically adds all users with administrative privileges [i.e., users who are members of group admin] to group boinc_master.)
If you need more selective control over which users should be in group boinc_master, you can use the command-line tool AddRemoveUser.
To add user1, user2 and user3 to group boinc_master, enter the following in the Terminal application:
where {path} is the path to the AddRemoveUser application.This also sets a login item for each specified user so that BOINC Manager will start automatically when that user logs in.
You can also use:
This is the same as the -a option and also sets BOINC as the screensaver for the specified users.

This also removes the BOINCManager login item for each specified user. If any of the specified users had BOINC set as their screensaver, it will change their screensaver to Flurry.
Installing BOINC on a Mac using the command line
In some situations, such as remote or automated installs, it is more convenient to install BOINC Manager via the command line instead of the GUI. But there is no way to respond to dialogs during a command-line install.
Apple's command-line installer sets the following environment variable:
The postinstall script, postupgrade script, and this Postinstall.app detect this environment variable and do the following:
- Redirect the Postinstall.app log output to a file /tmp/BOINCInstallLog.txt.
- Suppress the 2 dialogs (asking whether to allow non-admin users to manage BOINC and whether to use the BOINC screensaver.)
- test for the existence of a file /tmp/nonadminusersok.txt; if the file exists, allow non-administrative users to run BOINC Manager.
- test for the existence of a file /tmp/setboincsaver.txt; if the file exists, set BOINC as the screensaver for all BOINC users.
The BOINC installer package to be used for command line installs can be found embedded inside the GUI BOINC Installer application at:
Example: To install on a remote Mac from the command line, allowing non-admin users to run the BOINC Manager and setting BOINC as the screensaver:First SCP the 'BOINC.pkg' to the remote Mac's /tmp directory, then SSh into the remote Mac and enter the following:

So, you’ve decided to download an older version of Mac OS X. There are many reasons that could point you to this radical decision. To begin with, some of your apps may not be working properly (or simply crash) on newer operating systems. Also, you may have noticed your Mac’s performance went down right after the last update. Finally, if you want to run a parallel copy of Mac OS X on a virtual machine, you too will need a working installation file of an older Mac OS X. Further down we’ll explain where to get one and what problems you may face down the road.
A list of all Mac OS X versions
We’ll be repeatedly referring to these Apple OS versions below, so it’s good to know the basic macOS timeline.
Cheetah 10.0 | Puma 10.1 | Jaguar 10.2 |
Panther 10.3 | Tiger 10.4 | Leopard 10.5 |
Snow Leopard 10.6 | Lion 10.7 | Mountain Lion 10.8 |
Mavericks 10.9 | Yosemite 10.10 | El Capitan 10.11 |
Sierra 10.12 | High Sierra 10.13 | Mojave 10.14 |
Catalina 10.15 |
STEP 1. Prepare your Mac for installation
![TOLL Mac OS TOLL Mac OS](https://www.bemidjistate.edu/offices/its/wp-content/uploads/sites/60/2015/02/apple2.png)
Given your Mac isn’t new and is filled with data, you will probably need enough free space on your Mac. This includes not just space for the OS itself but also space for other applications and your user data. One more argument is that the free space on your disk translates into virtual memory so your apps have “fuel” to operate on. The chart below tells you how much free space is needed.
Note, that it is recommended that you install OS on a clean drive. Next, you will need enough disk space available, for example, to create Recovery Partition. Here are some ideas to free up space on your drive:
- Uninstall large unused apps
- Empty Trash Bin and Downloads
- Locate the biggest files on your computer:
Go to Finder > All My Files > Arrange by size
Then you can move your space hoggers onto an external drive or a cloud storage.
If you aren’t comfortable with cleaning the Mac manually, there are some nice automatic “room cleaners”. Our favorite is CleanMyMac as it’s most simple to use of all. It deletes system junk, old broken apps, and the rest of hidden junk on your drive.

STEP 2. Get a copy of Mac OS X download
Normally, it is assumed that updating OS is a one-way road. That’s why going back to a past Apple OS version is problematic. The main challenge is to download the OS installation file itself, because your Mac may already be running a newer version. If you succeed in downloading the OS installation, your next step is to create a bootable USB or DVD and then reinstall the OS on your computer.
How to download older Mac OS X versions via the App Store
If you once had purchased an old version of Mac OS X from the App Store, open it and go to the Purchased tab. There you’ll find all the installers you can download. However, it doesn’t always work that way. The purchased section lists only those operating systems that you had downloaded in the past. But here is the path to check it:
- Click the App Store icon.
- Click Purchases in the top menu.
- Scroll down to find the preferred OS X version.
- Click Download.
This method allows you to download Mavericks and Yosemite by logging with your Apple ID — only if you previously downloaded them from the Mac App Store.
Without App Store: Download Mac OS version as Apple Developer
If you are signed with an Apple Developer account, you can get access to products that are no longer listed on the App Store. If you desperately need a lower OS X version build, consider creating a new Developer account among other options. The membership cost is $99/year and provides a bunch of perks unavailable to ordinary users.
Nevertheless, keep in mind that if you visit developer.apple.com/downloads, you can only find 10.3-10.6 OS X operating systems there. Newer versions are not available because starting Mac OS X Snow Leopard 10.7, the App Store has become the only source of updating Apple OS versions.
Purchase an older version of Mac operating system
You can purchase a boxed or email version of past Mac OS X directly from Apple. Both will cost you around $20. For the reason of being rather antiquated, Snow Leopard and earlier Apple versions can only be installed from DVD.
Buy a boxed edition of Snow Leopard 10.6
Get an email copy of Lion 10.7
Get an email copy of Mountain Lion 10.8
Get an email copy of Lion 10.7
Get an email copy of Mountain Lion 10.8
The email edition comes with a special download code you can use for the Mac App Store. Note, that to install the Lion or Mountain Lion, your Mac needs to be running Snow Leopard so you can install the newer OS on top of it.
How to get macOS El Capitan download

If you are wondering if you can run El Capitan on an older Mac, rejoice as it’s possible too. But before your Mac can run El Capitan it has to be updated to OS X 10.6.8. So, here are main steps you should take:
1. Install Snow Leopard from install DVD.
2. Update to 10.6.8 using Software Update.
3. Download El Capitan here.

“I can’t download an old version of Mac OS X”
If you have a newer Mac, there is no physical option to install Mac OS versions older than your current Mac model. For instance, if your MacBook was released in 2014, don’t expect it to run any OS released prior of that time, because older Apple OS versions simply do not include hardware drivers for your Mac.
But as it often happens, workarounds are possible. There is still a chance to download the installation file if you have an access to a Mac (or virtual machine) running that operating system. For example, to get an installer for Lion, you may ask a friend who has Lion-operated Mac or, once again, set up a virtual machine running Lion. Then you will need to prepare an external drive to download the installation file using OS X Utilities.
After you’ve completed the download, the installer should launch automatically, but you can click Cancel and copy the file you need. Below is the detailed instruction how to do it.
STEP 3. Install older OS X onto an external drive
The following method allows you to download Mac OS X Lion, Mountain Lion, and Mavericks.
- Start your Mac holding down Command + R.
- Prepare a clean external drive (at least 10 GB of storage).
- Within OS X Utilities, choose Reinstall OS X.
- Select external drive as a source.
- Enter your Apple ID.
Now the OS should start downloading automatically onto the external drive. After the download is complete, your Mac will prompt you to do a restart, but at this point, you should completely shut it down. Now that the installation file is “captured” onto your external drive, you can reinstall the OS, this time running the file on your Mac.
- Boot your Mac from your standard drive.
- Connect the external drive.
- Go to external drive > OS X Install Data.
Locate InstallESD.dmg disk image file — this is the file you need to reinstall Lion OS X. The same steps are valid for Mountain Lion and Mavericks.
How to downgrade a Mac running later macOS versions
If your Mac runs macOS Sierra 10.12 or macOS High Sierra 10.13, it is possible to revert it to the previous system if you are not satisfied with the experience. You can do it either with Time Machine or by creating a bootable USB or external drive.

Before you do it, the best advice is to back your Mac up so your most important files stay intact. In addition to that, it makes sense to clean up your Mac from old system junk files and application leftovers. The easiest way to do it is to run CleanMyMac X on your machine (download it for free here).
