Apple Releases macOS Catalina 10.15.3 With Pro Display XDR Optimizations, Improvements to Multi-Stream Video Editing for 16-Inch MacBook Pro

I was planning to finally upgrade from Mojave, but I read here (and also in the Apple discussion forums) that the SMB problems are still there in 10.15.3. Also not sure if the Mail problems will be fixed.

I am staying on Mojave for a while :)

that's the route I went ... and I'm not experiencing any issues/problem that would force me to roll back ... been on cat. since its release .... '17 iMac, '12 mm, '12 mbpR (best laptop EVER!)

while it was a PITA to clean install, I took the opportunity to re-think those items I wanted installed on the host, and pushed everything else to the VM's ... trying to keep it clean

Agree completely.....thinking of buying a 2017 iMac Pro as well....making it the sixth 27" iMac and I will clean install again. Love my iMacs they just keep humming along and are trouble free. I made the switch from a PC to a (i)Mac in 2010 after one crappy PC system after another and there is no looking/going back.

I'm fortunate that I'm having fewer problems than some of you. But the problems I had with Catalina version 1, I still have--minus one-with version 3. I did a nuke a pave after version 2. That did not help. In fact it made one of the problems much worse. I even signed up, spent the money and joined the beta program. Should you might think that would help, it didn't, and AppleCare will provide no support if you are running a beta. FWIW, I'm running the top-of-line 2019 iMac with 128GB of RAM.

10.15.3 Combo is now noted on Apple's Download page, but it is linked to the same 10.15.2 Combo.
Click to expand...

If anyone is still interested, the Combo is now linked from this page:

Download macOS Catalina 10.15.3 Combo Update - Apple Support

The macOS Catalina 10.15.3 update improves the stability, reliability and performance of your Mac and is recommended for all users.
support.apple.com support.apple.com

Hover over the Download link on that page before clicking to make sure the link is to 10.15.3. You may have to refresh several times as the page may be cached if you've visited before.

Really a strange update experience this time with the page initially showing up with the 10.15.2 Combo, and that persists on one of my computers checking the download page. But once the hover showed 10.15.3 I was able to download and update.

I'm with you! I sat out both Lion and ML when they came out. Catalina may be joining them.

Same issue I was experiencing. Glad it’s fixed now. Thanks for letting us know!

I was going to install Catalina on 10.15.3, but I just going to skip Catalina altogether.

Hopefully, the next macOS will be a focus on stability

Same. I already experienced some painful issues and had to roll back to Mojave on two different Macs. Probably just skipping this release entirely as nothing it offers is worth the trouble.

1) on my old non-retina MacBook Air, subpixel font rendering has been trashed in Catalina, making text look crunchy and awful. I googled a lot, tried some terminal hacks, but the consensus was they just totally wrecked font rendering on older Macs;

2) on both Macs, I found out the hard way that having multiple user accounts on the same machine triggers a hideous bug wherein iCloud asks over and over for authentication. Each time it wants your iCloud password, plus a verification code from a trusted device, plus the admin account password, and even the unlock passcode from my iPhone. I re-verified probably a dozen times. It would stick for a little while but always ask again eventually.

Apple, this is unbeliveable. It's not about the fans noise - it's all about why the GPU is eating 18W of power for driving even single external display. I can't believe this is intended.

Without an external display the temps are 20 Celsius lower, by simply connecting an external display is not considered a workload for it to be over 60 Celsius on both CPU/GPU (due to GPU) - heatsink is just one piece so that makes sense to increase temperature on both CPU and GPU. But it is also increasing temps of the internal battery which is not something you want to do in a long run.

Also those who trying to to promote an idea that some utilities which disable Turbo Boost solved the problem. You absolutely don't understand what's going and what the problem is. Keep the utils installed and have fun with it, while the problem is still present. The problem is NOT CPU but rather GPU and power management.

Talking about power management. My power adapter burned during the update to Catalina (i waited until 10.15.2). So, I spent 80 EUR on a new one. Now i dont know why every time fans are working like crazy even when I browse the web.
on top comes issue with Messages. When opening a preview of selected image another image opens. It was a bit sad to see a 10 years old picture of my dog which is not alive anymore when I clicked on a picture of an A4
-document sent to me. Incredible.

I updated to 10.15.3. After the restart, as usual, it asked for my iCloud password. Then it asked if I wanted to backup my items to iCloud. And a window came up which was half off the screen and could not be moved saying I needed to upgrade my storage. Not able to see what I was getting, I said yes and it then proceeded to load the system, and the system expansions opened and hung the machine. Couldn't even force quit. So I hard shut down and restarted. It doesn't't look like my iCloud storage was changed......

BUT I suddenly noticed that I had TWO Documents folders. One titled "Documents", the other "Documents (Macintosh MacBook Pro)" and the documents were divided between the two. What was that all about. I had to consolidate the folders into one "Documents" folder. How did *that* happen?

You are kidding me. I’ve been back and forth with Apple support for hours and hours and hours. They escalated it to Cupertino. They assured me it would be fixed in this build. If that really is the case I will be getting a refund tomorrow without fail. 4K for a computer that does that ? Jokers

Did you get your refund?

It appears the auto dark mode bug where it wouldn't automatically switch when sunrise/sunset was enabled has been fixed. However, there's still about an hour delay where it would kick in 1 hour after my locations sunset time.

Sorry that has happened but thank you for mentioning it. I have a 2012 non-retina MacBook Pro and was very concerned about subpixel font rendering with the early releases of Mojave. I finally updated from Sierra to Mojave back last May when I felt it was safe enough. Now I guess I won't be updating to Catalina at all on this machine:

-subpixel font rendering
-losing access to 32 bit apps
-and problems people here have mentioned

The battery life on my 12" MacBook 2015 model has taken a severe beating after updating to Catalina. It randomly shuts down and then displays the low battery sign when I try to switch it back on, even when it's at 50/60/70%.

I know the battery needs to be serviced on a 4.5 year old MacBook, but this never happened before Catalina. As soon as I updated, the battery started acting up big time. Still no fix for this. Not to mention my MacBook doesn't read my 500GB WD External HDD anymore. An absolute cluster f*ck of problems.

Bug is still there and not fixed.

Unbelievable.

Whoof. Well, thanks for the heads up, at least I know not to try again.

Out of curiosity, are your two user accounts tied to different Apple or both to the same one?

In my case it’s the same Apple ID for both accounts (one is a bare bones distraction-free writing account) and I’m wondering if that’s the issue.
