You might do that before installing Pro Tools etc. At some point you may (or may not) migrate your existing user account from your old boot disk, you can do that using the system migration app, but do *not* migrate existing drivers or applications, just the user account. You install that new macOS, then boot from the external USB drive, then install Pro Tools, ILM, interface drivers and test it works, install plugins and test as you go. In the case of your computer with Thunderbolt but not Thunderbolt 3 that in practice forces you to go to USB SSD drives so I'd use a Samsung T5 drive ( ) And nowadays that shoud be the fastest SSD that you can support on your computer. If you have space on your current drives you can add another partition and do the new install there, but it is often simpler and safer to get a new external drive and install there. But basically you download the installer from the Apple Mac store and run it, but when it prompts you what to do you pick the option to do a new install not an upgrade. Tio do a full clean install: is too much to cover here on DUC and I don't know how much you know already. That would alter my plans about opening up the iMac and upgrading the drive or not. What internal drive is on that iMac is it a PCIe SSD or a HDD or a Fusion drive? The mac System Info utility will give you all that info). It is still not clear exactly what iMac you have, what is the Model number and SMC code (printed on the back), 21.5 or 27' display etc. Not sure what is going on there with you quotes, can just quote previous posts between and. Current versions of macOS will utilize APFS filesystems, be aware of that and any impact in sharing media between other systems. Then once all that is done and running OK clone that disk over the top your current boot partition. it may be time to crack open or have have somebody upgrade that iMac for you if needed.ĭo not shoot yourself in the head here, get a spare external SSD drive or partition and do a full clean install of macOS on that, installing clean copies of Pro Tools, ILM, plugins and other apps, testing as you go, then migrate the user account using the system migration tool (do not migrate apps or drivers).

And I hope you are not running on an internal slow HDD. Pay attention to those DRAM requirements. They you can run the latest available web browsers, latest available version for Pro Tools, etc. 21.5' or 27' How much memory? 16GB which is the max config is really the minimum I want in a modern Pro Tools system. Your Late 2012 iMac can install up to Catalina, I sure would not use El Crapitain.
