So far so good.

Music is up to 1.5.5.24, from 15.5.20. By the small build jump between Beta 1 and Beta 2, I assume this will be a short beta cycle. I guess public release in the beginning of May?
 
My M4 Max is bootlooping this morning after working fine yesterday. It was locked up this morning when I come into my office.

this fixed my safari issues from beta 1
Click to expand...

Mine got unusable but already in Beta 1 and it's even worse now. I run best in the 15.0 betas and got worse and worse with every new update.

Everything is just slow, beach balls when starting, even the Internet speed is much slower compared to Firefox when I run a test and when those messages come that an extension has been updated and I need to confirm it somehow again the whole Mac gets unresponsive for a while especially when there are two messages at once, what often happens.

I think an M4 Pro with 64GB and a M3 with 24GB should be enough to run a simple browser and it does with every other one.

It must be the Profiles in combination with extensions, they only have to be there and everything and everything is much slower. I'll delete them and try if Safari without Profiles is working better or if it's the combination of more extensions and using Profiles is the problem. Before I always had only one extension.

There were better versions before, where I had no problems using Profiles and more extensions than usual.

I have the Apple Passwords extension and a 3rd-party extension for Firefox to use "Hide my Email", the last one needs to be logged into iCloud, what's annoying with Container Tabs, because every container needs his own login. And I purge my browser data every few days.
Nothing got slowed down using Container tabs what is like Profiles without separating the extensions.
The original Firefox even the latest Nighlty is also the only browser that still is able to run the 1Password 6 extension, it can't fill anymore but there is some advantage to just clicking on 1Password mini in the Menu Bar, it still can save new logins automatically that way.




Edit: Without Profiles now it is running much better. Still slower than Firefox but at least not unusable.
