I also had the issue on a MacBook 13" M1 and Monterey 12.6 / Xcode 14. It was a nightmare, it took me two days of countless retries! In the console log I could see it kept failing with the following message: [ASServiceBroker]: Connection interrupted LaunchPad:-[LPAppManager(StoreSupport) _acceptStoreConnection:]_block_invoke app store xpc message error: Connection invalid got event: Connection interrupted But it was not only an issue of sleep because I was using my computer while updating. I was using VSCode at the same time, which was trying to call git, not working since packaged with Xcode which is unavailable during the update... So I stopped using the computer and did the update with the recommendations I could see on previous posts: plug the computer (this time I used the Apple power adapter and not the USB C cable from my external screen) In battery settings --> Power Adapter --> I ticked "Prevent your Mac from automatically sleeping when the display is off" It was long but finally it worked! I did not try caffeinate as recommended in previous post but it could be a good alternative to altering power settings. Previously I also tried to restart the updating process (kill it, delete Xcode, restart, clear app store cache) but apart re-downloading 12gb it did not seem to help much!
