I am trying to Update the OS from macOS Catalina 10.15.3 to 10.15.4 on my Macbook Air 2014.

Every time I click on Update Now Button for updating the OS, a prompt appears saying

"To Update You must restart your Mac"

However upon restart, installation doesn't happen.

I have been trying to install but am ending up with restart multiple times. There is no progress with the OS upgrade.

Please help

Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login and launch your installer.

or download direct the combo update—Combo update macOS 10.15.4 https://support.apple.com/kb/DL2037?locale=en_US

I had this same issue for weeks and finally realised it’s because I didn’t have enough disk space/storage. It needs 20gb of free space before it will install. I deleted things and optimised photos etc, stored in iCloud and freed 35gb... it then installed the very next time. Not sure why it I didn’t tell me I didn’t have enough space but there you go.

I wiped my laptop completely and did a fresh install-it worked but it was a bit painful

The only “fix” that has worked for me was to completely wipe my 10.15.4 MBP internal SSD and then install 10.15.3 from an external drive. (Note: I was not able to find .3 anywhere on the Apple Developer site. They used to have all of the previous versions there. Why were they removed?) Then I recovered my data from a TimeMachine backup taken the day before the 10.15.4 update. My reason for updating to .4 was it reportedly had fixes for Catalyst development. So much for that.

I had the issue for a number of weeks, my MacBook rebooting at random and half a dozen times a day.

Reinstalling the OS was the only solution. It took a couple of times to get everything installed correctly..

A mission indeed!

There is a major problem with Catalina 10.15.4 and 10.15.5. Lots of people are having the same or similar problems. Me personally I brought a brand new MCP 16 at the beginning of April 2020 and it was absolutely brilliant for about a month or so. Then (after it must have updated to 10.15.4 without me knowing about the emerging problems) it started to kernel panic on a daily basis. Every time I leave it idling and the screen goes to sleep it crashes and restarts itself giving the error message 'Thunderbolt power on failed'. I've tried almost every resolution in the book but It still does it about 3-4 times per day. I've been on the phone numerous times to Apple and they basically just shrug their shoulders and say it's a software problem, we're aware of it we'll try to fix it. I think it's absolutely shocking that I've paid £3000 for a brand new laptop and I'm supposed to just accept it's not going to work properly for the foreseeable future.

Another thing I've noticed in the last few months as well, the battery performance definitely isn't as good as it used to be when I first had it. And I'm not one of these users that abuses the battery and doesn't look after it properly. I always make sure I use the battery properly to maintain it's lifespan. However it seems to me there is something in 10.15.5 that is diminishing the battery much faster. For example the battery in the first month of ownership used to last 11 hours comfortably. I'm not a heavy user. Now it lasts 6-7 hours if I'm lucky. I'm fairly sure it's nothing I've done to the battery, I haven't used the computer any differently to what I did in the first month of ownership. I've tried disabling the battery health management function and it hasn't made any difference. In the time it's taken me to write this post (20 minutes) it's used 7% battery. I've got no way of proving this now but when I first had it I estimate it might have used 3-4% tops in that time.

Mine was acting up also, I downgraded the OS back to High Sierra, then it has been working perfectly.

I also made the mistake of updating to 10.15.4. Most of the Apple apps hang with "not responding." I am looking all over the Apple website for 10.15.3 but can't find it. What a mess! Two days spent so far trying to put my MacBook back together again. For God sake, Apple, don't you test this stuff before you ship it???

Do NOT install 10.15.4.

How do I get back to 10.15.3?

I have installed Catalina 10.15.4 on my MacBook Air 2014 and subsequently it reboots when not in use.

Every time I open it up I have to log in and it has restarted and all applications are closed.

I did install Microsoft Teams recently but the issue of rebooting started before that I believe.

Has anyone got a solution?

I am afraid this hasn't worked for me-I ahve tried 3 solutions mentioned in this thread. The update is already downloaded it just suppsedly requires a restart to install but keps asking for a restart. Using safe mode made no difference, trying PRAM reset as suggested elsehwere no help everything is slower and some apps not loading properly now too... Is smeone able to fix this? Many thanks

sadly not an option for me. have tried all options offered again (bar the wipe my drive option)-my macbook tells me I am running 10.15.2 but 10.15.4 was downloaded and installed but just needs a restart...and on it goes

Everything is slower but if I disable automatic updates I can avoid the annoying pop up each time I log on and will sit it out and wait for a fix from apple I think

I have had this issue for the last couple of weeks since installing 10.15.4. After trying all the listed options surrounding Energy Saver and Sleep modes, I contacted Support. Twice they helped reset chips (PRAM etc. I don't even know what all) with no resolve.

All they advised me to do was to turn off my MacBook every day...

I also hope for a fix as I don't want to go backwards.. Anyone?

So Have you sorted it. Since I downloaded Mac OS Catalina on my Mac book Air (2015) it has been restarting everytime, failing to come up for days also.

Please how did you reinstall the OS. Mine was on High Sierra before I updated to Catalina. Since I updated my Mac book goes off everytime also fails to Come up several times.

Hello

so after several attempts not working, I had to downgrade my OS back to High Sierra, it has been working perfectly since then.

tho I lost all my files.
