MP 7,1 MacOS Tahoe on a Mac Pro 7,1

I know eventually I will install a Tahoe partition on my 7,1 as it's the last version of the OS the 7,1 will support. My question is, is it ready for prime time now? I figured I'd wait until the release of 26.1 before pulling the trigger, but is there any reason to avoid 26.0.1?
I'm on Sonoma 14.8.1 now; skipped Sequoia as I typically upgrade my OS every two years. Everything just works for the most part., so I'm in no hurry, but I suspect it's inevitable that I upgrade -- just want minimal drama.

The forums are fraught with stories of how 26.0.1 messed up this, that or the other. Since you mention you don't have a real itch for 26 point anything just yet I'd say hang tight and wait a few weeks after 26.1 goes live.

I have the latest version on two 7,1 machines and it is working fine on both of them. I know that doesn't mean much in the face of all the negative reports elsewhere.

I'm on 26.1 Beta 4 and it looks alright. 0.1 was slower. Definitely feels a bit slower than Sequoia. If it's a production machine maybe wait for .3?

Since macOS 26 is the last macOS supported for 7,1, I assume Apple will get it to a great place.

So I installed the release build of 26.1 about 3 weeks ago and so far it mostly works.

Some observations and comments:

The dock does not deal well with items on different drive partitions, forgetting them occasionally.

Some of the new icons are taking some getting used to.

The AMD RX 6900 XT driver seems fairly solid.

Getting my old ML-3312 Samsung laser printer working was a chore. Minor drama -- I hadn't realized Samsung had sold their printing division to HP, but the generic HP driver provided with the OS for the LaserJets just worked. Apparently when HP took them over they rolled the Samsung driver into theirs.

The column view tweak to automatically resize to the filename width is something I've been asking for since the NeXTSTEP 2/3 days (i.e. back when the underlying BSD layer was known as "Tahoe" -- not kidding). Mostly works too.

Music force migrating my library to the new version and deleting the old one was annoying -- didn't expect them to botch this like they did. This was really the only major piece of drama in the migration as I was working on a playlist in Sonoma and the migration made *everything* disappear when I booted back into Sonoma. Thankfully it was completely intact in Tahoe, but I can't go back.

I suspect this OS won't actually be mostly done until 26.3, but that's normal. That said, it's livable, and the column view change alone makes it more usable. You don't need to hold off if you're on a 7,1, but there's no need to rush into it either.

How is your performance so far? Mine becomes fairly laggy with Liquid Glass and "clear" icons enabled. So I just enabled "reduce transparency" and disable "clear" icons (using Default in appearance) and it feels more like Sequoia.

I'm on .2 Beta 3.

I am on 26.1 beta, only because I've been just absolutely flat out with work so have not updated.

The thing I dislike is the slight lag in opening applications fly-out, but going from what you said, I just changed them to:

And that has completely resolved that, now instant again for no real visual difference that matters. I had clear selected before.

I'm running at the moment two 5K screens and a third 4K screen because of the work I'm doing needs that many windows open. My desk is looking like mission control at the moment.

Great to hear that resolved the lag. It's definitely related to Liquid Glass. On Intel machines like ours it seems to have a worse impact since it doesn't seem optimized well yet. On my M1 Max having defaults on with "clear" I see no issues. I am also running dual Studio Displays at 5k and our systems are powerful enough to handle it obviously, but macOS 26 is so unoptimized it makes me not get work done properly until I did below.

I posted this in another thread, but this should help you get better performance:

Quick (Temporary) Fix:
  • Install .2 Beta 3 (Beta 4 should come next week and then Beta 5 and final in mid December)
  • Enable "Reduce Transparency" under Accessibility > Display
  • Enable reduce motion in "Reduce Motion" under Accessibility > Motion
  • Disable transparent icons if you have that enabled under Appearance > Icon & Widget Style > Set to "Default"
  • Disable window tinting under Appearance > Tint window background with wallpaper color

This pretty much made my system feel like Sequoia .7. I'll re-enable these "features" (lol) once macOS 26 is in a better place. I just need to get work done and Liquid Glass literally slowed my system down to a crawl.

Ok, on further review, this was only mostly true -- the generic driver didn't have duplex printing support at all. Thankfully, the last published Samsung drivers (Ventura timeframe) still work if you can get them installed.
 
Random questions with regards to Tahoe on 7,1:

- Anybody have experiences positive or negative using with a Pegasus3 R6 ...?

- same question with regards to: Sonnet M.2 4x4 PCIe Card w/ 4 Samsung 970 2TB EVO Plus drives?

Any insights appreciated.

No experience with the Pegasus3, but I can answer most of this about the Sonnet + Samsung. I had this exact configuration until just recently.
I swapped out my Sonnet 4x4 card for the Sonnet 8x4 card right before the the Tahoe upgrade -- that's working great. Also, the reason for doing this was I needed more storage -- I retained the 4 Samsung 2 TB 970 EVO Plus drives I had on the 4 x 4 card and they are working as expected. I added in 2 8 TB Sabrent drives and they work great too on the same card. So not quite the same but fairly close now.

Cool, thanks very much! The 8x4 looks like a great card but just not at a stage where I'm upgrading anything in 7,1. It's been a good 6 year long run, will probably keep going for a decade like previous 5,1's - just running apps I need to keep using and utilizing the 768GB RAM I have installed.

Will update to Tahoe in a few .point revisions, just trying to see ahead of time what problems to expect. If Pegasus doesn't work, I guess 10gb ethernet to NAS can replace.

Turn off Liquid Glass using the procedure I posted in the post above you and everything should be smoother. Turn it on perhaps in .3 or .4

Did this and it's still running like crap. Not seeing anything unusual in activity monitor, but constant beachballs. Will probably reinstall this weekend. If that doesn't fix it, then proxmox.
