Any Mac geeks here? Tearing my hair out trying to (unofficially) upgrade my 2017 machine with Open Core Legacy Patcher

[Sandrine1982]

Hi there. So Apple (and subsequently my employer) have decided that 2017 machines will not longer be supported with security updates from the end of October. Now I've been logged out from all the systems on my Mac and i'm having to use a company PC which is massively slowing down my work, I've always been a Mac user and I just hate PCs!! I've been trying to solve the problem by upgrading to Sequoia with OCLP based on a video on Youtube, but despite following all the steps religiously, it hasn't worked. I'm stuck on a loop where my Mac just goes back to recovery mode instead of completing the installation. Has anyone had experience with this and can you help? TIA

Firstly a 2017 machine is fairly old, especially for macs as they moved to the m-series processors like 5 years ago?

Secondly if it’s a work device then just get your IT department to sort it out. There might be admin settings you can’t control, or terminal privileges you don’t have access to, or enterprise software causing issues. This is firmly not your issue to resolve

My IT department won't help as they gave me a PC to use (they don't give out Macs, it was my personal one). The Open Legacy Patcher is is an "unofficial" workaround so that I can still use my Mac. You think a 2017 machine is old? It's working perfectly, and it's much quicker and smarter than the PC they gave me. I despair ...

I feel your pain, but sorry I can't help with "OLP", but wondered if you have been "logged out from all the systems on my Mac", why do think it's likely you'll be able to log back if upgrade to Sequoia?

Do you know that they will still permit to use Mac OS if you upgrade? If you'e unsure are you able to confirm by trying it on another updated computer running a more recent OS?

I feel your pain. In my experience Macs are so well built that they seldom die, they just become obsolete because incompatible with current software. I have a perfectly good functional 2007 (!) Macbook, a 2011 iMac that we use for viewing Internet shows because it’s too slow to have all my files open at once, a 2018 AirMac that is presumably also going to lose its security updates soon (that’s my occasional out-of-office device) and the M1 iMac I work on full time. None of the feckers are ever going to actually die.
I‘m registered to some big Mac user online community precisely for this kind of query. They tend to know most things, but occasionally explain it in a way that goes over my non-teccy head.
My main concern with getting your 2017 device to run on Sequoia is that it would be unutterably, painfully slow for actual work.
