It’s highly unlikely Apple will ever give us an iPad that runs macOS — and that’s OK. Because with a few tricks (that do not require a jailbreak), you can easily install Mac OS X on your iPad all.
Several tools are available for Macintosh System Administrators, mostly in the form of command-line shell scripts to be run from the Terminal application. Please read the comments in each script for descriptions and directions.
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:
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.)
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. Make happy from scratch.
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.

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.
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.
To remove user1, user2 and user3 from group boinc_master, enter the following in the Terminal application:
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.
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:
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: Video slots online.
To get the latest features and maintain the security, stability, compatibility, and performance of your Mac, it's important to keep your software up to date. Apple recommends that you always use the latest macOS that is compatible with your Mac.

If a macOS installer can't be used on your Mac, the installer will let you know. For example, it might say that it's too old to be opened on this version of macOS, or that your Mac doesn't have enough free storage space for the installation.
To confirm compatibility before downloading, check the minimum requirements for macOS Catalina, Mojave, High Sierra, Sierra, El Capitan, or Yosemite. You can also find compatibility information on the product-ID page for MacBook Pro, MacBook Air, MacBook, iMac, Mac mini, or Mac Pro.
Before installing, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available. Learn how to back up your Mac.
It takes time to download and install macOS, so make sure that you're plugged into AC power and have a reliable internet connection.
Safari uses these links to find the old installers in the App Store. After downloading from the App Store, the installer opens automatically.
Safari downloads the following older installers as a disk image named InstallOS.dmg or InstallMacOSX.dmg. Open the disk image, then open the .pkg installer inside the disk image. It installs an app named Install [Version Name]. Open that app from your Applications folder to begin installing the operating system.
Follow the onscreen instructions in the installer. It might be easiest to begin installation in the evening so that it can complete overnight, if needed.
If the installer asks for permission to install a helper tool, enter the administrator name and password that you use to log in to your Mac, then click Add Helper.
Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar, or show a blank screen several times as it installs macOS and related firmware updates.
You might also be able to use macOS Recovery to reinstall the macOS you're using now, upgrade to the latest compatible macOS, or install the macOS that came with your Mac.
