How to run 32 bit plugins after Catalina: Install MacOS Mojave on an External Drive

[@jdsosa879]

Thanks for the Video! My question is . Can I install drivers for my Audio Interface that is not compatible with Catalina ? I upgraded to Catalina and now my ResidentAudio T2 doesn’t work because I didn’t realized it’s not compatible with Catalina. Would this help and how?

Hi JD. Thanks for the supportive comment! I would be inclined to say that it will probably "work" (since it's a completely separate instance of the OS, but has access to the hardware ports), but I wouldn't advise doing so. The reason is that the interface is used for recording audio "on the go" - whereas the OS will be functioning on an external drive with much lower read/write speeds - so latency issues may crop up, defeating the purpose of the drive (unless its on a thunderbolt SSD itself - but that's getting into expensive territory). If you aren't dependent on Time Machine backups, my recommendation would be to try and format your Mac to the OS it came with, and use part of the process described above to load an older Mac OS version of the same HD as your original Mac. Read ahead only if you are fairly confident with your computer. Someone on YT has probably done this, but if not, the rough steps would be: a) Manually back-up your Mac (not using Time Machine) b) Follow Steps 1-3 in the video above to create a bootable installer for Mac OS Mojave. c) Restart with Shift + Option + Command + R that will install the version of macOS that came with your Mac. If your Mac is fairly new and you're happy with the OS, STOP here and you should be able to hopefully use your interface with this older version. If you need a version that's somewhere in between then d) Restart again using the option key like in 15:28 in the video and use the bootable installer to load Mojave on the original Macbook (not a separate external drive this time). All this being said, I haven't tried this - so please, please do proceed with caution, and do let me know how it goes!

I found someone on YT who demonstrates the first part of this process that would be helpful: kzbin.info/www/bejne/fpnWhHmwr6aihqs

@@bacchusbarua I have two internal Ssd one of them is empty and formatted for that purpose following this Video, by the way; awesome way of putting this video together and the explanation is fantastic. One of the best tutorials

@@jdsosa879 Thanks JD! That's a really smart set-up you have! Although it's impossible for me to test myself, based on your set-up I'd say go for it [just make sure to load the new OS on the correct one ;) ]. Once complete, you should be able to boot directly from the second SSD and should have access to all your ports (as well as your interface). Do let me know how it turns out - and wishing you the best of luck!

Great video, I made the High Sierra installer and Lives flash drives. I put them in my 2015 mbp everything was fine till after it asked for my Apple ID. I put it in then hit enter and now its stuck with a message so I had to shut down my mac and wait and see if I have done something wrong any suggestions would be most appreciated

[@bacchusbarua]

Hi Madge. So sorry to hear you're having difficulty. It's a bit challenging to diagnose without the specifics - do you remember what the message was? The only things I can think of to double-check are 1) That the installation was performed on the Lives flash (17:34) 2) You are connected to the internet (16:12) 3) When you put in your Apple ID it might be trying to load some excess data from your iCloud drive if you have a lot on it (in which case you need to uncheck that option). These are guesses though as I don't know the exact situation - but I hope they help.

Good Stuff and extremely well done. Thank you!

[@ilzbilz9730]

does this work on m1 pro/max?

[@bacchusbarua]

Hi Don. Sorry for the delayed reply. Unfortunately I don't have an M1 so cannot test and answer this. I'll be getting one in January and will try. However, a recent article from Macworld suggests it might not be possible "Sadly, the answer to this question is no. While Big Sur is able to run on both Intel and M1 chips, none of the previous versions of macOS are compatible with Apple's new processors." www.macworld.co.uk/how-to/can-m1-macs-run-old-macos-3802190/

[@ravekitchen]

With BigSur , youd be lucky to run your 64bit plugs also "if not signed" , way to go appeL
