macOS 15 Sequoia on Unsupported Macs Thread

[esculapio1]

I've tried OCLP 2.0.0 with Sequioa on both my 2012 Mac Mini 6,2 and my 2013 MBP 11,1 and they both work great!
I love that even the Memojis work again.
The new retro Mac dynamic wallpaper seems to work well on my Mini but it does not seem to want to load on my MBP. I thought these were all video files but this one seems to be different

Hi there, that's great news. My mini is running well on Monterey but i was worried about Sequoia. I did a fresh install it on USB 3 flash drive (to make sure it could install without trouble) but it is painfully slow there.
Do you notice if it is much slower compared to Monterey or older OS?

Reverted patches on sequoia beta 7. 1.05 gb update to sequoia 15.1 RC went without issue (still WhatsApp doesn’t like my system but that’s to be expected) everything seems fine . MacBook Pro mid 2014 OCLP 2.1 nightly.

What did you revert to and what Mac do you have?

Have updated original post .

Same here: I tried to update, as usual, with the root patches installed, but the “Update” button in Software Update was unresponsive, both the direct one and the one in the “More Info” window; maybe the Kepler no-license-agreement-window bug seems to be more serious in Sequoia (in Sonoma, sooner or later it always started to update anyway, but now I had to revert the root patches: no big deal, but annoying anyway)…?

Hopefully, what you are experiencing is not related to translation, but I've seen issues with translated subsystems since my first experiences with Linux back in 1995. Although English is not my first language, I've been using it since then.

Yes, language-related issues seem to be rather frequent, on different OSes: but probably have nothing to do with Photos pausing iCloud sync too frequently (which instead seems to be more related with a too hot Mac).

Hello. I have a problem with synchronization in the new password app via WLAN. Synchronization only works via LAN. Internet via WLAN works perfectly. My device: MacBook Pro 10.1 Retina Midi 2012 macOS 15.0.1, OCLP 2.0.2

 

[deeveedee]

Smooth upgrade to Sequoia 15.1 Beta 24B82. Patched with OCLP 2.0.2.

I see you've not tried the MBP 13,x series! Mine still has big issues with iMessages beachballing and no iMessages Cloud syncing.

Are there any settings to fix this?

I think you will have to give more information on what you did to arrive at this - which version OCLP, did you create an installation flash drive, did you do post-installation boot patch, were you patching a beta, or the RC, etc, etc...

General question:
Does anyone at all on a version of Sequoia have working iCloud Safari favourites over wifi?
It looks like a few people on the internet on supported Macs have issues with this too
so probably/maybe not a OCLP error. But grateful for any hint, as I have so far been unsuccessful at making this work on any Mac at all. Fine on Sonoma on all same Macs.
Many thanks.

I have the same problem and I’ve tried all the solutions without success, but I haven’t found any topics of people with supported Macs having this issue, except for occasionally reading here that supported Macs also have it. Where did you read about it?
Has anyone installed 15.2?

I didn't understand, I thought the known issues were referring to favourites sync, but you were only talking about 15.2.

Working here, but have to have both machines plugged in to ethernet. This makes syncing favorites intermittent since the ethernet connection (Thunderbolt 2 ethernet adapter) on the unsupported rMBP10,1 drops sometimes, for reasons unknown so far.

Yes, sorry I was unclear, I meant over wifi and have corrected my post. Works over ethernet here also. Many thanks!

Kernel Debug Kit 15.1 build 24B82 is released also MetallibSupportPkg 15.1-24B83;-) 👍 new 2.1.0n from yesterday! So maybe final 15.1 will be 24B83 next week. Update: macOS 15.1 24B83 RC2 is just released!

2x MacPro 5,1 and MBP 14,2 OTA RC1 -> RC2 without problems (and RC2 seems more responsive then all betas before) other macs will follow, if there's some time left before weekend with newest 2.1.0n (and also newest KDP Metallib if needed) - FYI

This just as an FYI and for those who are not aware as it solved an issue I found with running an external monitor in Sequoia:

Whenever I started using the app MonitorControl 4.2.0 in Sequoia I can use the build in brightness/volume keys to control the 3rd party monitor settings in closed lid mode.

Smooth upgrade to Sequoia 15.1 RC 24B83. Applying post-install patches with OCLP 2.0.2.

Thanks, that also confirms my synchronization problem with passwords over WiFi.

I have a couple of issues I can't find direction on maybe you all can help me.
I have a Mac mini Server 5,3 on 15.0.1 16 gigs of ram and both drives were replaced with SSD's
Before I upgraded to 15.0.1 the TV app worked fine and I could use home sharing now the app crashes as soon as I open it .
I went back to 15 same issue came back and even went to 14.7 issue still there.
I also can't connect to my MacBook Air M2 or my Windows 11 pc in networking I can see the Windows computer but get this error .
Any help with these issues would be great.

There are so many factors implied that is almost imposible to formulate an hypothesis. At least, that is pausible.
