Finder in 10.15.4 is auto-popping up when wifi connect is specified to outlying devices (iPad, iPhone, etc.) ... annoying
 
Why is that nowadays Mac OS updates take way too long? They used to take 10 minutes, now it's half an hour at least. Installing the OS for the first time on an empty disk even takes less time than this.
it should be related with the saturated internet globally. Be patient

Man, with all the issues folks are reporting by upgrading to OS 10.15.4, I am definitely going to do a clean, fresh installation of OS 10.15.4, and then migrate/copy needed files, folders, settings, apps, etc. from a "clean", just completed SuperDuper! backup.

Most of the complains are related to delays and stoping the prices during installing. And the cause of these are the globally saturated internet. Be patient

My EGPU seem to work much better. But while the HDR mode automatically was turned on, only real HDR content is shown properly. Apple should have created a HDR mode for the desktop. The LG TV does not seem to recognise that it is in HDR, but still HDR10 video clips displays correctly. Interestingly macOS created a new calibration for my TV automatically for the HDR mode.
 
Still hoping it fixes how fonts are displayed on non-retina screens

It might have...my MacBook Air 2013 looks better and did not have to go to terminal to turn off font smoothing. Hope this is finally fixed!
 
Using mission control, clicking on a full-screen app still brings the app forward but does not switch to it as the active app. Meaning shortcuts will go to your previous app.
 
The good news is that the nearly 90 minutes it took my machine to install the update is worth my LG HDR 5K Display working correctly when my MBP wakes from sleep. No more having to unplug / re-plug to get correct resolutions! Huzzah!

HDR doesn't quite work right, but hey good effort! Guess we'll see how that evolves with coming updates.

Oddly, though, I think I may have a dead ThunderBolt port. Port 2 on the left side will not respond to anything plugged in. Doesn't seem to be throwing any errors, and doesn't show any power output using System Information. 🤷🏼‍♂️
 
I have some early optimism that this seems to fix the standby issues with my Dell U3818DW ultrawide monitor.
No more having to plug it out of the combined power/display usb-c cable to avoid it waking up all the time making the "connected" sound.

Fingers cross it really is solved.
 
the safest way to download is directly from APPLE SUPPORT PAGE. then save it to your SSD or HARD DRIVE
this way you always have a copy
downloading it from system preferences I do not do
Always good to keep full copies of OS updates on a drive or THUMB DRIVE
never know when you loose internet and need the OS

Note that the full installation file for OS 10.15.4 is not there. For that, one needs to use dosdude1's program.

Also, no matter which file you download, it is wise to make a copy of it to another location on your internal drive/SSD. Myself, I have a folder entitled "Updaters", and a subfolder entitled "OS 10.15 and Upgrades". In that folder now is the full installer file for OS 10.15.3, and one for OS 10.15.4. I will be doing a fresh, clean installation of OS 10.15.4 on both of my Macs on Sunday, but on Saturday, I will make my usual 2 SuperDuper! backups for each of my Macs onto 2 separate external SSDs, and that OS 10.15.4 full installer will then be there also.

Upgrading a 2018 MacMini. I downloded the Combo Updater. The installer said it was preparing the update and then said it had to restart. After restart I'm stuck with a black screen. Anyone know how to fix this?

OK, sorry to ramble on, but maybe some folks will get something (or maybe a lot) from all that.

If some folks didn't, they certainly should. Great post.

Here's another gotcha. Remembering username/password for an increasing number of s/w providers. That would include for MS Office 365, Adobe "everything", including older stuff you installed from CD. Where did I put those darn Adobe legacy boxes with the serial numbers on? Better have 'em ready.

One more for luck: Have a lot of bandwidth available if you're going to have to re-download a lot of stuff. The "Estimated time remaining 4 days..." message will ruin your day, or week.
 
Has anyone else noticed a difference in the appearance of black and deep shadows when switching between AMD graphics and integrated on the 16” MBP? They clearly updated the AMD drivers because the blue tinting issue appears to be fixed, but it’s disconcerting that switching the drivers makes such a marked visual difference to deep shadows. I’ve not noticed visual differences from the drivers on any other Mac before this new 16”. Why isn’t there consistency on this “latest and greatest”?

I also don’t understand how colour profiles change the appearance of total black. Surely that is the one “colour” that should be consistent across every profile. Both the colour profile and display driver should be telling the monitor to block as much of the backlight as possible to achieve its deepest black. The response for everything else depends on the response curves in the profile. So why the difference in the appearance of black between profiles, and now, the driver?

If you have a 16”er, you can test these observations by setting the Wallpaper to a “Solid Colour” and choosing the black option or one of those “colour bomb” pictures.

Apple is supposed to have the best colour management software and operating system, but lately I’m not so sure.

i never even thought of this. if i have a 1tb HDD that plugs in via USB on a mid 2014 Macbook pro i7 (16gb 512gb) ssd - what would my exact process be?
1.) Use CCC to make a copy of my drive from my computers HDD to External HDD
2.) Boot from External HDD
3.) Update to Catalina and test everything out
4.) if okay with update - go back and make a CCC of your old system on the external HDD as a backup
5.) Install Catalina on internal HDD
6.) Celebrate?
That is exactly what I do with every major macOS release. I know at least one other person here has posted a more complicated procedure which I personally think is unnecessarily fussy.

I actually have done this with Catalina through Step #3.

I just updated my evaluation external drive to the latest Catalina 10.15.4 on my Mac mini 2018. I am still not sold on Catalina and I still need to occasionally run a 32-bit application. For the time being I will stay on Mojave.

Even if I do eventually upgrade to Catalina (maybe in September), I will likely always keep a Mojave boot drive around for those legacy 32-bit apps.

That person is me. It depends how careful one wants to be. As it is, someone reported issues using the OS 10.15.4 Combo Updater on a late 2018 Mac Mini. Well, that is the exact machine I have. So, this is just another confirmation for me to do a clean, fresh, virgin installation of OS 10.15.4, followed by a migration of files, folders, settings, apps, etc. from a SuperDuper! backup.

As it is, a number of folks prefer to go the "shortest" route (I could have used another word, but no really needed), via an upgrade in place, and if it works for them, fine and good. I am not going to criticize them. But, one will eventually pay the price if they always follow the upgrade in place route, especially after doing it for a number of times. Besides the possible issue of third party compatibility, there is also the chance that some files, folders, etc. will be left over that really no longer need to be there.

I upgraded an external Catalina 10.15.3 evaluation drive to 10.15.4 using the Combo Installer on my Mac mini 2018 with no problems.

This was a CCC bootable clone of my working Mojave drive upgraded to Catalina.

In any case, when I do an installation of a major macOS, I always use a bootable USB thumb drive.

I see no reason to wipe the drive clean. I'd rather upgrade a functional clone of an existing production drive since in the end, that's the way I'm going to upgrade anyhow (apps, user accounts, user data, etc.).

It's not like I'm going to install Catalina on an evaluation drive and reinstall everything from scratch to get to where I am right now on Mojave. I have better things to do with my time.

I also have better things to do, but need to respond to your somewhat narrow minded remarks.

First of all, except in this rare case now, when I move to a new Mac OS, I first make sure my full, complete prior system is "lean, mean, and clean". And I use SuperDuper! for my backups. Got that, or is that too difficult for you to grasp?

Secondly, I DO NOT do a reinstallation of everything. It's obvious you do not know how to read. Whenever one does a complete, fresh, "virgin" installation of the Mac OS, they are offered the opportunity to migrate (ie, copy) needed files, folders, applications, settings, etc. from a backup (whether Time Machine or not). So, and hopefully this is CLEAR, I point to the just completed SuperDupe! backup for that process. The machine/system then does the work of doing that migration. Got it now?

Third, when I boot either of my Macs from their respective SuperDuper! backup, I actually do not need to use Disk Utility to Erase and Format my internal SSD. The clean installation of the Mac OS actually will first Erase and Format the drive.

Fourth, for this new version, I would typically download and install the OS 10.15.4 Combo Installer. But with how long it's been since OS 10.15.3 was released, and with a couple of minor issues I am having, I want to do a clean, fresh installation.
[automerge]1585189081[/automerge]
So you do a clean fresh virgin install every time? Just wonderin'...
No, not every time. Typically, when I am "moving" from a prior Mac OS to a new one (like from Mojave to Catalina), I will do a clean installation. WITHIN the same Mac OS, I will typically download and install the Combo Updater. However, with the same Mac OS, I will do one additional (typically with the last version) clean installation.
 
So you're putting your trust in 3rd party software to be smart enough to a) put back only stuff that's required, i.e. no broken and/or unlinked leftovers from long ago crashes, b) not malware, and c) restoring everything the app needs to function, including possible configuration changes, squirreled-away keys, p/w's etc

Would that be a fair summation?

I would not extend that degree of trust to a utility package, ever. Call me cynical. I'm a utility s/w developer! Not in the apple space though. I trust me, of course. Everyone else's stuff is highly suspect.

Migration assistant, which is what is being used, is an APPLE product. You can actually see the program inside your Applications folder, which contains the Utilities folder. If I can't trust an Apple product to do such a task, what can I say?

I have had this yesterday too, on my MacBook Pro 15,4 (2018) with Mojave 10.14.6, after I installed new Mojave Security Update. I restarted with resetting Parametric RAM (command+option+P+R) and ThunderBolt 3 port is back alive. I don't know what helped, maybe a simple restart is enough.

Has the update been pulled? I've just checked again, and no update available (in Belgium).
 
Well, something in this update broke Paperless (3.0.71). It will no longer open libraries. Happened on both of my systems. Also found it forced HDR on my 2nd monitor (attached to iMac via USB C). Really hosed up the color profile. At least you can turn that off.

Have you come up with any resolution on the Paperless issue? I just downgraded back to 10.15.3 for now.
