Unable to install macOS High Sierra 10.13.3 Update

Hi,

if so did Apple a mistake? I think 17C2120 was just the 10.13.2 full install version (?).

Did the engineers tell you this?

I'm also stuck with it at 10.13.2. . Will try the full installer upgrade like you suggest.

Thanks.

The automatic upgrade to MacOS 10.13.3 got stuck. I got 3 attached screens. I tried to restart in safe mode, no success. Then from my Time Machine backup holding down the option key. No success. Then after about an hour my MacBook Pro 13" 2015 started up all by itself (miracles happen?). The MacOS is still 10.13.2 (17C205). After 50 minutes "preparing" my Time Machine finally started a new backup. In the Apple Store app on my Mac I get the message there are no upgrades available. When I go directly to the website of apple store, 10.13.3 is there, but it won't upload on my Mac.

Now what?

Brand new out of the box iMac Pro,10 Core, 32G RAM, 16G VRAM, 1TB SSD, MacOS 10.13.2. Logged into iCloud, so basic email, messages, etc. NO additional software installed... going to do clean install of everything, if the stoopid update will ever run.

- Tried App Store Update, Update Error 600

- Downloaded 10.13.3 Update for iMac Pro, gets stuck on "Preparing...", never asks for restart after 45 min, Checked the Activity Monitor barely using any CPU or Memory but not showing hung, tried 2x.

- Tried the - trash, hold down keys, reboot process by Gazzzar nothing special happens'

- SO ANNOYING, new computer and have gotten nowhere, I'm certainly not going to allot of trouble to set the thing up until I can do something as simple as an update on a totally clean machine.

Yes... me too... and on a BRAND NEW MACHINE. Only difference, I didn't get the option to simply have it restart back to 10.13.2. I had to ERASE my Hard Drive, and reinstall from my Time Machine record from an hour earlier.

Why is 'brand new machine' in all caps, you ask? Well, I had to buy a brand new iMac, as after I installed High Sierra on my previous iMac, which by the way worked so incredibly well, it constantly shut down. At first, it was once a day... then it was several times a day... finally, it wouldn't stay lit long enough to even start it in recovery mode.

Why didn't you take your machine to Apple to have them diagnose the problem, you ask? Well, I tried, but there was not ONE OPEN APPOINTMENT with the Genius Bar for 2 weeks... and I needed a computer sooner that that.

I'm sorry, I don't meant to rant... BUT I'm becoming increasingly displeased with Apple as of late. Will I try to install the 10.13.3 update again. NOPE... can't afford yet another new computer !!!

Exactly same problem here. iMac 27" 5K retina (Spring 2017) with 10.13.2

Following the usual update process to 10.13.3, and once it finished (with a couple of typical restarts), the system remains at 10.13.2 (?!?!?)

No errors. Just as nothing occurred…

First time I see something like this… :-/

Took most of a day but eventually managed to re-install macOS via the full internet download. In between lots of failed and hung installation attempts. Now on 13.3.3 but my iMac is running so slow that it is almost unusable. A bit better after I had let iTunes check its library (took all night) but even then single applications running are extremely slow. What now?

I have this same problem. I've tried to download and install the 10.13.3 update on my Apple MacBook Air, currently running 10.13.2 (17C205) several times, but each time it fails and I get a message that "some updates were not installed Automatically". Any ideas?

Same issue here. MacPro 6,1 with macOS 10.13.12 (17C2120) installed. Doesn't appear to be any way to update it to 10.13.3. The update is not showing in software updates and the downloaded 10.13.3 installer dmg from the apple site shows me the same message with the link to the beta.apple site.

No idea how to solve this one..

PS to my earlier post... I just got on my MacBook Air a short time ago, and when I activated the screen, something didn't look right. It appeared that some type of load process was underway. This screen changed shortly after that, and the sign in screen came up. I signed in, and then noticed that I no longer had a notification indicating that an update was available. I then checked my system but it still indicated that my macOS High Sierra version was 10.13.2. Shortly after that, the notification indicator appeared agin on the Apps icon and once again, it says that the update to 10.13.3 is available. I'll try to load the update again, but I'm not hopeful. Any help would be appreciated.

Same here. White MacBook on 10.13. Tried to update to 10.13.3 on the App Store, but every attempt failed. Downloaded the 10.13.3 Combo Updater. Ran the package, but after the required restart the MacBook simply shuts down. After restarting, it’s just stuck forever on The Apple logo with no progress bar. Start up in recovery mode, select the internal drive as Startup disk and it does start, but still running 10.13.

I give up. Wasted too much time already.
