Don’t think I’ll ever purchase a piece of technology that will last as long without issues from day one till now ever again .
So, I asked this a few days ago, and no one has provided any feedback. Does anyone have any experience with this in terms of: "is sticking with an older version pre Sequoia" more reliable for unsigned apps? Approving MakeMKV hasn't presented any issues, but I am still curious long term, if I should stick with an older version for these types of apps.
I think it's just more cumbersome to approve things on sequoia. Other than the extra steps I haven't noticed any difference.
Thanks @Kevo I tend to stick with older software unless I need something current, or third party / cross platform software. So, I thought it was good to find out the better solution here.
Hey, I need help. I have macbook air 11 Early 2014, Is there a step by step guide anywhere i can refer to to install Sequoia?
Thank you.
Thank you.

Also, you might want to consider installing Sonoma instead of Sequoia for a mac of that age, especially if you have performance issues with Sequoia, but the linked tutorial is the same for both versions.
Does 15.7.1 have anything worth updating to it? I'm waiting for the installer to show up so I can install from USB so root patches are automatically re-applied vs OTA.
I'd also suggest that you install Sequoia on an external SSD drive, like a Crucial X10 Pro or Samsung T9.
That way, you can continue to run your last supported macOS (11 Big Sur) and boot to the external drive to run the newer apps when you need to... (or vice versa, install Sequoia/Sonoma on your internal drive and keep Big Sur on the external drive as a backup).
@MacMorrison I was curious about that, is there any difference in installing two different versions on the same physical drive, but separate APFS volumes vs 2 separate physical drives? I have Monterey, and Sequoia installed on the same 2TB fusion drive, but on separate APFS volumes, and they just share the space allocated to the whole drive. I can boot separately, and unmount the one I'm not using as two separate drives. I was just curious if there was any functional difference.
Not at all, in my opinion. In general, macOS is going to run much faster on internal SSDs (and the Fusion Drive as well), so I'd recommend that to anybody with enough drive space.
The Fusion Drive is a bit of a time bomb because Apple has removed official support for it in macOS 26 Tahoe... it's possible that the OpenCore developers can restore it, but there are no guarantees right now. Definitely make sure to keep all your Fusion Drive data fully backed up in case of problems.
Most people bought Macs with insufficient SSD storage (high prices), so that is why I advocate for external drive installs. Trying to create large enough partitions for macOS, your apps, and data is difficult if your boot drive is too small to begin with. Also, it creates more wear on the SSD's NAND cells, dropping the life expectancy of the drive.
It's a good idea for people to become familiar with using external drives, especially while they're still relatively inexpensive and faster than network backup. They're important for Migration Assistant and Time Machine, and a good backup in case your internal drive melts down entirely. You can literally run your Mac from the external drive if its SSD goes bad (but not if there is something else wrong, like the processor or logic board).
Some external drives can rival the performance of internal drives in the older Intel Macs - you can take advantage of USB 3.0 and Thunderbolt 1-3 speeds with fairly established storage options and much larger capacities.

Thanks, yes I've had 3 versions of macOS installed at once, ran fine, hate having to reboot into the one I want to use, so I try to keep it to one version, 2 at most to reduce reboot needs.
My next question is, does the existing 15.6 KDK still work with 15.7.1? Apple never released a newer Sequoia KDK beyond that one. It's been fine for 15.7, so just checking to see if I should wait.
I would wait. There's no documentation for 15.7.1 yet and it's probably just a minor security update.
I don't know the answer to the KDK question... when I first tested installing macOS 15.6, there was no KDK for it yet, just 15.5. I think it takes a few weeks to see a new KDK release after each macOS update.
I noticed that Apple put the refurbished M4 Mac Mini (16GB, 256GB SSD) on sale recently and that might be a good spare/upgrade Mac for anyone who needs a new one quickly.

Installed 15.7.1 without issues. 15.6 KDK used and the root patch date was successfully updated to today.
Edit: Safari 26.0.1 also applied successfully after macOS update. Using it now to post this edit.

Based on this video from Zollotech:
The most likely only fix in 15.7.1 is the font rendering security hole mentioned here.
Trouble-free update to 15.7.1 24G231 on MBA 6,2 using OCLP 2.4.1.
Last 15.7.1 dev beta 24G309 was not updated on a MBA 3,2 and remained at 24G309.
... along with the usual plethora of 26.x updates for other supported devices. All good so far.

Another buttery update to 24G231 using MacOS standalone installer and OCLP 2.4.1.
I've been working on getting my Monterey environment set up. I installed it, and just left it for a while. Plus I wanted to switch back for a bit because I was having the fan kick in more when watching video, and wasn't sure if it Was sequoia, or what. Well turns on it happens with the supported OS too.
So, I have two stable installs, the latest supported by OCLP, and the latest officially supported by Apple.
Edit, thought I would add I also like having more flexibility over my desktop pictures under Monterey vs Sonoma, or Sequoia where I have to keep the menu bar light to prevent the reddish tint issue. It's not OCLP related, but it's still annoying.

Likewise on MBA 6,2 (see sig).
Adding: bouts of the fan spinning up post-update as various daemons listed in Activity Monitor do their things. After a couple of hours that settled down.
Yes, I think the fans spinning up is a result of the new macOS system indexing Spotlight and running other background tasks post-install. It settled down for me too, after a few hours.
Did the update to G231, yet another update popped up in system prefs/ software update
Edit: This one installed G309.

Same here. Smooth update to G309. Although it didn’t show up as beta.
Is it possible to treat macOS like Linux, or another Unix system in terms of fstab, and stop all my Volumes from auto mounting? E.g. when booting into Monterey, can I stop the "Macintosh HD" volume with Sequoia from automatically mounting, and vise versa ?
