I can only use it for 11 days

Doh! 🤣

M.b. try some Asus USB-BT dongle? I`m using one with cMP 5.1 + AppleLED Cinema (27"). Installed in Cinema port - works well (but I don`t have such earphones).

Mu cherished 27 Imac 2012 is no longer viable. A local Apple guy with some used ones was a bit shocked when I showed him a pic of the Computer info and pointed out that Sequioa was the start-up disc, he did not know about OCLP.

He has two late 2015, 5K 27 inch Imacs for sale one is i5 3.3GHS with a 2tb Fusion drive, the other is i5 3.2GHS with a 1TB HD. I have read some negative things about fusion, and am wondering if it is a problem for OCLP. My current HD is only 250 gb's I use an SSD for Time Machine. There is not much difference in cost, but I am wondering for every day use which is the best one. Any advice will be appreciated.

I have a 3.4 GHz 27" 2017 iMac with a 1.03Tb Fusion Drive.

Sequoia 15.1 beta7 installed fine with OpenCore Patcher 2.1.0 and Modern Wireless post-install patches. It is rock solid.

It works well installing by USB Key and not by macOS 😉

On my models, it actually works quite well also from within macOS, OTA: it’s only that on the MBP11,3 the license agreement is not displayed (probably Nvidia Kepler issue)…

 

[Sven G]

Good find!
I can confirm that using ethernet makes this work here too. The iCloud tabs has worked all along but not the Safari favorites. One might guess something in OCLP might need a little love perhaps. Hopefully it can be fixed at some point.

On my MBPs, it also often happens that the Apple Photos iCloud sync is paused, due to a “poor network connection”; while the Wi-Fi signal is actually quite strong: so, a Sequoia and/or OCLP patching issue? or maybe some router or ISP issue, who knows…? BTW, Photos also often displays a “Mac has to cool down” message, even if it isn’t hot outside (this happens mostly in clamshell mode): and also this of course pauses the iCloud sync.

I've got a 2011 Macbook Air 13" that I use infrequently when I'm taking meetings outside the office. I've been running Monterey on it for a while using OpenCore with no issues.

Recently I was goofing around and decided I'd try Sequoia. I upgraded to OCLP 2.02 and then did an upgrade from my Monterey install.

The install worked, the system boots and runs, albeit a bit slow. BUT if it goes to sleep when it comes back I get the screen looking for my password, enter the password, the screen goes black and then I get the screen looking for my password. The only way out of it is to reboot.

Suggestions? (other than go back to Monterey that is)

2013 6,2 MBA here (two of them, oddly). Did you try resetting the PRAM three or four times in a row? Set OCLP to the specific model rather than the generic host? In the OCLP settings there are checkboxes for sleep issues in some machines. Maybe that would apply to yours?

On my MBAs I've got Sonoma on the primary machine and Sequoia as a test installation on the other. Initially I had sleep issues with Sonoma but some combination of fixes and dumb luck fixed them. I run into a freeze now and then every couple of days, but with a restart I'm good to go again. The Sequoia machine ran slow and had low-rez graphics until I went through some restarts and post-install root patching. It's fine now, but I use it only to update to release versions and see if it seems worthwhile to update the main machine. So far I've held off because of some glitches with Sequoia (not many, but some) reported here, and because we're not even at the x.1 version of the latest macOS.

FWIW my "daily driver" is a 2012 imac 27" and I'm running Monterey on it right now. I have a 2011 iMax 27" that I have Sequoia running as a test machine and it seem ok. I'm not a huge power user but the '12 seems quite capable. It's an i7 of some sort, but if yours is not you can upgrade it with a bit of skills. Once you open the machine, go for it. (and give it a good cleanout, there will be all kinds of dust on the heat sinks and fans)

Unless you are really going for some heavy duty usage, fill up the memory on your 2012 and then get and install a big PCIE SSD into it, if you want to leave the HDD in the machine use it for backups or other stuff. And the performance will be very reasonable.

Have you investigated the 'log stream' output already?

Have you tried the 2.1.0 nightly? It might be worth your while, as it appears the devs have taken a decision to
"Disable mediaanalysisd on Metal 3802-based GPUs Intended to maintain long term stability" from the changelog
Not entirely sure what it means for general Photos usage but I assume less scanning for things like face recognition and such, but it looks like a candidate for less issues with Photos. I am using that nightly on one MBA 7,2 and it does not seem to affect my Photos usage in a way I notice so far at least..
FWIW, YMMV.

I take advantage of this little License issue, to talk about two strange behaviors that have appeared with Sequoia and that I have discovered other friends of mine with different Macs have as well.
I have this theory, based on what has happened from Big Sur to the present: early versions of macOS, from XX.0 to XX.3 or XX.4, are not optimized at all, so OCLP suffers.
As soon as Apple "fixes" macOS, as usually happens around the third or fourth upgrade, then the OCLP Developers are able to optimize OCLP as well and everything works, even in our unsupported Macs, as if by magic.

That said, dear @Sven G and other MacRumors friends, even with Sequoia XX.0.1 everything works satisfactorily for me. However, I am very annoyed by:
1) the absence of the layers graph in the Preview application (and the fact that the Auto Levels button doesn’t works and if I touch its side sliders the image disappears and turns light gray)
2) the very strange behavior of AirPlay only with YouTube from the iPhone since in most videos it produces a gray background with a ban sign in the middle. But mysteriously, with other videos (obviously still from the same iPhone and YouTube, of course) AirPlay works fine! A sign, perhaps, that this is not a limitation of the Kepler video card, but a possible blocking of content or other issues. Am I wrong?

Unfortunately, I can't overcome shyness and dare not ask the Developers to devote themselves to these two small problems, insisting here and on Discord until I know that the Developers have acknowledged the two problems. The fact is, once fixed, late 2013 iMacs would be equal to the latest Intel-supported iMacs. Max performance aside, of course... So, a great and extraordinary victory

With Sequoia 15.0.1, if I try to start the installation from the USB stick, the installer crashes after accepting the license agreement; I suspect, perhaps, because the Wi-Fi is not active?
So with macOS Sequoia 15.0.1, I would not know how to do it in case I (or other friends) urgently needed to restore everything from scratch via USB stick.
Unfortunately, I could not find a solution. Thanks for the help!

EDIT 2024-10-19 20:57 GMT +2
The friends @Ozzie1910 and @Ausdauersportler responded me on Discord and suggested that the problem I described may be because the installation language is not English. (In my case it is Italian). Hurray!

EDIT 2024-10-21 08:57 GMT +2
Yesterday I then tried to redo the installation by selecting the English language, instead Italian and the installation no longer stopped and continued.
The strange thing for me, since I had never done it before, was to find macOS always in Italian, even though I had chosen English...
The only change I found was in the technical specifications -> Wi-Fi as OCLP had entered the FCC US form instead of IT.
I remedied this by manually correcting the EFI "config.plist" file, rebooting and re-enabling EFI-Boot with the Option key when the Mac restarted.

I would like to say thankyou for all your hard work. I have a MacBook Air from
2017. A dual i5 with 8gb of ram and macOS Sequoia runs great. Thankyou.

 

[next_cube]

Installed Sequoia (OLCP 2.02) on my Mac Pro 2013 (fresh install via USB) yesterday. Everythings works fine except of Filevault (internal error) and icons show up no more on the desktop after I tried to enable Filevault.

I also had the issue that WiFi was not working when I tried to update to Sequoia from an USB stick with Open Core Legacy Patcher.

Since I do not have a clue how to report this to the team, I did upgrade in place from MacOS Ventura to Sequoia on my MBA 2013 with 1.3 GHz Core i5 CPU and 8 GB RAM. Worked fine but it was a system that had nothing on it but MacOS Ventura.

Thank you very much for your post @houser . My wife's MBA 7,2 are presenting the same symptoms described by Swen G. The only solution I could find so far is to connect the iPhone through a USB cable and import new photos from the Photos app on the MBA.
I thought that the MBA 7,2 used only 31001 GPU features therefore the changes in OCLP 2.1.0 would not affect the laptop, but now reading an old post on Kronokernel's blog (https://khronokernel.com/macos/2022/11/01/LEGACY-METAL-PART-2.html) he mentions that "Only Metal 1 GPUs will occasionally use 3802, but the majority of the time rely on 31001".

The development of OCLP has been stalled for 2 weeks, I hope they're working on a big update...

Yes, the short version is that we are all spoiled rotten

The mac crashed tonight while sleeping.

My problem was that the Mac crashed after about 3 hours. This happened the first two nights after upgrading from Ventura to Sequoia. I found this by looking at activity in some of the logs. It occurred during the night. I used the

pmset -g

command and discovered that the `standbydelaylow` time was 3 hours. I changed it to close to 24 hours with

pmset -a standbydelaylow 86300

I booted into recovery and deleted the `/var/vm/sleepimage` in case there was something wrong with it. It was remade at the first reboot.

Since then, the Mac has not crashed. After not crashing for two nights, I ran

pmset restoredefaults

and still no more crashes.

 

[Sven G]

… So, in some way, the Photos sync pausing problem resolved by itself, also after some basic troubleshooting (see deep NVRAM and SMC reset, trying with an Ethernet cable, and also reverting from OCLP 2.1.0n to the stable 2.0.2: even if this is probably irrelevant): now, syncing has resumed also via Wi-Fi, even if (!) now it wants to re-sync the whole Photos library. Something similar had happened also in the past, so I don’t think it’s an OCLP problem: rather, some form of iCloud issue, who knows…? (BTW, it’s also clear that driving an external display in clamshell mode can heavily influences all this (often with the fans on and a hot Mac): maybe more in Sequoia than before.)

Interesting (and I, too, have an Italian system)…

In any case, the MetallibSupportPkg installer (don’t know if it’s included in an OCLP-created USB installer flash drive) can also be downloaded manually before the install and stored on an accessible disk (and thus, if needed, it can be installed manually before the root patching):

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.

I continue to struggle for the 15 to work on a MacBookPro11,2. After freezing on the login screen (which I overcame by deleting ~/Library/Preferences). Now Safari freezes when starting. And because of this, applications that use Web-kit do not work.

 

[amaze1499]

Update done via OTA to 24B82 using 2.1.0n no issues.

Having said that, I’m getting the no start-up sign on boot up more frequently now which is easily being resolved by a hard reset.
