macOS High Sierra stuck on Calculating... in App Store

I tried to download macOS High Sierra via App Store and clicked Download on its actual app page. The Download text just changed to Calculating... and it has been like that for a very long time (and nothing appeared on my Purchased List of my account).


I'm using MacBook Pro (13-inch Mid 2012) running on 10.12.6. The macOS High Sierra didn't appear on the available updates page. I tried to update Keynote/Pages/Numbers, it was downloading apps but it wasn't updated to the latest one (Keynote 7.3), it was just 6.0.1.


Is there a way to possibly reset the Mac App Store? I've tried signing out too. The account works fine on other Macs (Mac Mini and MacBook Pro Retina) so I was wondering why it's not working on the old one.


Thanks in advance.

MacBook Pro, macOS Sierra (10.12.6)

It may be that the Apple servers are a bit overloaded: a lot of new and updated software now.

Yes, you can download it on another mac. Make a TimeMachine backup before you upgrade !!!!!!

Do you have a SSD in the MBP 2012, or have you the HDD?

If the SSD, I would wait with HighSierra, the APFS conversion is automatic and can not easily be reverted. There are a lot of issues.

"The weird thing about this is, consequently, when I tried downloading the same installer on another Mac (MacBook Pro (Retina, 13-inch, Early 2015)), the download progresses (and even completes) unlike the one being troubleshooted now"

Did you download on the MBP2015 from the same internet connection?

"Do you think it's okay to use the installer downloaded from this machine to the 2012 one?"

Yes, the download is not machine specific.

Hi Lexiepex, thanks. Yes, I know that, the problem is that when you click Download, it's just stuck on Calculating... There's no progress message or anything denoting that it's really being downloaded. I even checked the network monitor but there's no impact on the connection.


There is still 30GB+ free space so that shouldn't be a culprit. I was thinking now to just download the installer from another Mac then use that to install High Sierra. Is this setup just fine?

I see. The weird thing about this is, consequently, when I tried downloading the same installer on another Mac (MacBook Pro (Retina, 13-inch, Early 2015)), the download progresses (and even completes) unlike the one being troubleshooted now. So I don't think the Apple servers are overloaded.


In the case of the MBP 2012, it is running on HDD. The MBP 2015 runs on SSD and has a copy of the installer. Do you think it's okay to use the installer downloaded from this machine to the 2012 one?


I am still hoping that the App Store issue can still be resolved because this can possibly happen to other apps (e.g. Keynote). Thanks.
