Have tried several times to update to 10.7.5 on MacBook (10.7.4; 2.4 GHz Intel Core 2 Duo; 4 GB 1067 MHz DDR3)and get error message about how 'expansion' unsuccessful, that download may have been corrupted. Please advise. This is also the case with other updates that need to be made such as iTunes 11. Please advise.
MacBook, Mac OS X (10.7.4), 2.4 GHz Intel Core 2 Duo
Ok. Here are the instructions to follow to try and solve this problem:
1. First Exit Lion Installation.
2. Then go to applications folder.
3. Find the file name "Install Mac OS X Lion" and Delete it.Then restart your mac.
4. Go to the app store.
5. Go to purchases and click redownload Os X Lion.
If It Shows that it is already installed then press and hold the option key when you click on the purchase tab. If It still doesn't happen then use spotlight to search and install the mac OS Lion.
Hope this helps 🙂
There's no need to waste resources installing the full update installer from the MAS. DL and install the10.7.5 COMBO update. It's only 1.9 GB.😉
The problem I have is that I downloaded the 10.7.5 combo on both the target MacBook (new 10.7.0) and my iMac (10.8.2). Both download the ~2GB file successfully but the image won't mount, says corrupt. How can that be?
Wonky Internet service. Try wired if using WiFi.
Unable to update to 10.7.5
