Getting an error after downloading 15.1
Failed to prepare the software update. Please try again.
An error occurred while downloading the selected updates. Please check your internet connection and try again.
MacBook Pro 15″ 2018
OS 15.0.1 (24A348)
Internet is fine, 60gb free space
Appreciate any suggestions
MacBook Pro 15″, macOS 15.0
Same here
MacBook Pro 13" 2019
OS 15.0.1
Could it be M series only going forward? Seems like the Intel models aren't working.

Good morning,
same here on Intel Macbook Pro 16" 2019. I think, I solved by switching the content caching in system setting on/off.
Look at System Settings -> General -> Sharing -> Content Caching.
Found the trick on other forum, It sounds that the switch on/off deletes a download cache, if one of the last try of an update fails.
I’m on a mac mini 2018, so intel Mac. Cant’ update to 15.1. Not running any vpn or AV
Download succeeds, but the hang in preparing for quite a while and eventually failing with the aforementioned error.
I tried;
I’m at a loss here, need my Mac for software development, so any more help/tips would be welcome! 🙏
Worst of worst cases
Terminal command below
softwareupdate --fetch-full-installer --full-installer-version 15.1
Manually download the FULL Version
There are factors:
Some which are beyond your control and those with are totally under your control
Slow wifi connection
Too many other people downloading at the same time and Apple Servers are overloaded
Software on the computer interfering with the download process including AntiVirus Software
Notation: Disabling the AV Software may or may not solve the issue.
Removal of the AV Software may increase the chances of the download to perform as expected.
Running behind a VPN which may increase Packet losses or corruption of the download
If via wifi & too many Other devices using the wifi at the same time reducing the Bandwidth to your computer.
Best Results are via Ethernet Cable to Router
Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal
Try Again using the Software Update Applet in System Preferences / Setting
Worst case - Restart in Recovery Mode and choose Reinstall macOS.
This in theory will pull the latest version of macOS this computer qualifies to run
Thanks
No VPN, no AV and laptop connected via Ethernet cable directly to 1GB hub.
Recovery mode option is too drastic for this. Shouldn’t Apple fix the upgrade?

Updated 3 Different Apple Silicon computers from 15.0.1 to 15.1 on the day of release using the Software Update applet
Done over Wifi 6E via a 1 GB Up / Download Speed from ISP
Arrive at you own concluding as to the Remedial Actions needed to achieve the desired results
This implies, there was No Need for Apple to Fix that which was not Broken, in my setup
This is a pain, but I'm certain it will work. It worked on ALL of my 2018 Macbook Pro's, and I have lots of those machines:
1) IMPORTANT: make a full Time Machine B/U of your Mac
2) Restart your Mac in Recovery Mode using ONLY the key combo: Option+Command+R, hold these keys down until the Apple shows up asking which WiFi network you want to use
3)Select "Reinstall MacOS Sequoia", and follow the prompts to do so. DON'T WORRY! Using this restart key combination will install the LATEST MacOS your machine is compatible with, and it will NOT delete or overwrite your applications or your data!! (But you have the Time Machine B/U anyway) If you end up with Sequoia 15.0.2, then your machine can't handle 15.1.1. (HIGHLY Unlikely) Be prepared for this to take literally hours (all day or overnight), depending on the throughput speed of your WiFi.
4) Once finished, go to the Apple>about this Mac and check the MacOS installed. It should now be 15.1.1. For some reason downloading and installing from Recovery Mode work where using the Software Update option in Setting does not.
Hope this helps!
I was able to fix the issue by reviving my MacBook Pro with another MacBook Pro. Afterwards, I was able to perform the update to 15.1.
Make sure to revive, not restore:

I had the same issue with this upgrade as others reported on my MacBook Pro 16" 2019, Intel core. I tried most of the options in this thread first but they didn't work. Not sure if it was persistence but I got 15.1 to install eventually by:
Definitely recommend taking a full backup before trying any of this as there were some odd noises at the end of that 15.0.1 re-install.
Any update? i have MacBook Pro1.4 GHz Quad-Core Intel Core i5 plenty of storage and internet bandwidth
I’m having the same issue with 2018 MacBook Pro. Could this be an Intel chip set issue? Others on this thread reporting success are noting 2019 MacBooks, which are probably Apple M series chipsets. I’ve spent about 8 hours on this issue & yes, maybe it’s time to do the MacBook machine upgrade shuffle.
Same here. 2018 MacBook Pro 13inch four thunderbolts 3 ports. 2.3 GHZ quad core intel core i5. Tried safe mode, same error. Tried recovery mode and installing sequoia again, same error. Contacted apple and they have no idea how to fix it besides erasing my Mac and starting from scratch. Any ideas? I already tried turning off “find my Mac” and cache sharing…. At my wits end since nothing seems to be working.
I finally decided to resort to internet recovery. My files are in the cloud anyway. So erased my disk with the disk utility, then installed 15.1 from internet recovery. That worked! But now Xcode is giving me troubles.
All this doesn’t bode well for any future Sequoia updates, fingers crossed …
I’ve been having same issue. Tried twice. Was reading through this thread for tips on an ipad…when I looked up and saw the installation had moved on and successfully installed 15.1. Maybe give it time and see before taking drastic action. I have a 2019 iMac
