My MacBook pro is stuck on "setting up your Mac" part it's been over an hour now.

This happened to me yesterday. I have a MacBook Air and after downloading and installing Yosemite, it was stuck on "Setting up your Mac" all day.

I eventually got in touch with Apple Support and resolved my issue in about ONE MINUTE. Here's how:

1. Power down the computer.

2. Plug the computer into a power source.

3. Press and hold the following three keys simultaneously: Shift + Control + Option.

4. While still holding Shift + Control + Option, press and release the power button.

5. Release Shift + Control + Option.

6. Power on the computer.

My computer booted to Yosemite and I've not had a problem since.

Hello there,

I had the same problem with my Mac Mini, the install would do just fine but then at the setting up your mac screen it stalled for hours. (Literally, I gave it overnight to finish up). It did that twice, (I even installed from a flash drive and formatted my hard drive)

So just to test something, I reinstalled OSX Yosemite and skipped all the sign into my apple account stuff. Instantly my mac was ready.

So for me the fix action was to skip all the sign into my apple account. Maybe that will help you all.

Thanks

This part seems to be quite slow, doubly so if you have a lot of files.

I have the same problem too

Nevermind, I did a test reinstall with Yosemite on the same Mac Mini with a different 500GB hard drive, and it hung again even skipping all of the icloud/apple account setup. I thought the drive was bad, but I was able to Install Ubuntu on it and it works flawlessly...

I guess I am going to put Mavericks back on the Mini.

This completed the installation. Everything is now working perfect.

Just wanted to say thank you for your post glatzsa ! That stupid screen has been driving me nuts and your post got rid of it for me! Thanks again 🙂 🙂 🙂

Thank you!

Thank you! 😁 Thank you! 🙂

Thanks, glatzsa. It worked for me, too. Slight twist. After boot up, the sign-in screen appeared. Then, it took me to "accept/decline" re use agreement, then to the desktop.

Thanks @glatzsa it solved my issue in a minute too!! 😀

Thanks @glatzsa, one-minute fix for an hour long boring screen "setting up your mac" applied to me as well. You saved my other few hours of search for solution as well.

Thank you very much, I was starting to think I had a bad Disk. Did exactly as glatzsa suggested,

Power down the computer, Press and hold Shift + Control + Option simultaneously, press and release the power button and release Shift + Control + Option and my system came right up.

Tks again 🙂

Thank you so much for this. I had the same problem on an iMac 24. I recently a hard drive crash on my iMac 27 with significant data loss (thank the Lord for Time Machine backups). I have to admit, I was nervous following the advice of a user thread vs. just calling Apple, but I decided to live on the edge and go for it. Totally worked for me too! THANK YOU!! 🙂
