View Full Version : Mac OS X installation error

Mar 31, 2013, 06:43 PM

I have a Macbook Pro (Mid 2010).
I've tried to install the Mac OS X Mountain Lion after formatting the disk using the disk utility and the following error had occurred:

An error has occurred during the installation of Mac OS X
Try to re-install

I also tried to install Mac OS X Lion in the original HDD and after replacing by a larger one and the same issue has happen.

I am getting very frustrated... Any help would be much appreciated!
Thanks in advance!

Shut down.

Unplug. Let sit for a few minutes or better yet, overnight.

Re plug in. Reboot. Try to install again.

One thing I've learned is that I should restart my Mac more often even though I very very rarely have issues.

Boot into recovery, load utilities and launch disk utility. Erase and repartition the drive, and then reinstall. All should be well after that.

How are you installing ML? I would get an 8GB flash drive and create a ML install USB.


After making a ML installer, you hold the Option key while booting and select the USB key. I would selct Disk Utility and wipe the partition and then reinstall.

Thank you all for the feedback but the problem persists.

I've erased and re-partitioned my drive before installing (hfs+ journaled). Then, tried to install ML using a 8Gb flash drive and nothing occurred.

I re-did the first step and tried to install Lion using a DVD and another time nothing happened.

I really don't what to do. I don't believe that my Mac OS X sources, both Lion and ML are corrupted because I arrive to install it in my iMac today.

More tips?
