Mac os x lion stuck on apple logo

I really have to reuse this post because I have the same issue and perhaps found another way to solve it. But I want to understand why this way may work. So why does the exact copy of the system boot from external HDD and not from the internal one? I think there might still be issues with the permissions. When I tried to fix them on the "broken" Mac, there were several error messages, telling me some permissions were not able to be fixed. Perhaps it repeats its magic and everythin will work fine again.

Or you know by reading my descriptions, what this magic is and I can perform it via terminal or disk tool without having to erase my system? Hard ware issue can be detected by running disk utility. If your hard drive is falling, You should immoderately attempt to back up all the information on your computer on prevent losing valuable business data such as contacts ,Email ,Projects and invoices.

Shutdown your computer ; restart and then hold down the "Command -R" keys untill you see the OS X Recovery utility screen.

I have lost count how many times I have had to do this. As I had upgraded from leopard I suspected it was due to legacy system settings or simply overloaded with startup items. You would think this would fix the issue as the only software installed on the machine was a clean install of lion. This improved the speed and reliabilty a great deal, however it didn't get rid of the spinning wheel issue. Reading about other similar problems with Lion someone recomended repairing disk permissions using the Disk Utility app incorrect records of software files installed.

Surprising I had any permissions errors given I had erased the drive but there were many - this did reduce the frequency of the startup problems. The next suggestion was to clean up the system caches. I used an app to do this but you can delete them directly suggest you google how.

This appears to have fixed the issue. But has not been very long since I did this.

Fingers crossed. It could always be the logic board. I've had to replace mine twice once every two years. First time covered by apple care. It's a known issue with the last silver keyboard MBP model. There's a class action lawsuit as it appears apple put these machines out with a known issue with that particular logic board and most owners of that machine have experienced the issue.

Omar Rosales. The lawsuit alleges that Apple knowingly sold defective Logic boards. Most of the problems are due to a manufacturing defect as these models were made in China. Lately, Apple has had a slew of defective products to include Iphone Antennas that didn't work, power cords that fray and spark, Nvidia graphic cards that don't work, etc.

So, its par for the course.

Otherwise, you can proceed to basic disk and permissions repair by booting from your original operating system disc.
