My MacBook Pro won't boot up. Circle slash logo appears after the apple.

Same thing just happened to me. White screen with black apple logo and spinning slash logo. Is this a dead HD? I haven't tried disk repair yet.

Boot up from your * System* DVD #1 & run the _Hardware Test._ _Look on the DVD label to see which key to use to boot from in order to run the Hardware Test._
Post back the results.

Hi. Same thing happened to my '09 Macbook Pro. After Apple logo comes up, there is slash logo that just keeps on circling around but doesn't go anywhere after that.

I did disk repair, and hardware test also. Result was 'all ok'. I even tried to re-install original Mac OS X using the DVD that came with purchase (using Previous Folder option to keep files), but it says that since I had updated Mac OS, it can't be downgraded with version on DVD.

Any ideas? I would really hate to format my hard drive. Thanks!

"(using Previous Folder option to keep files)"

No such option in an archive & install. Do you mean the "preserve user preferences and data" option?







"since I had updated Mac OS, it can't be downgraded with version on DVD."

Your system info shows you are still using Mac OS X (10.5). The last Leopard version is 10.5.8 I believe.
Are you positive that you used the System DVD that _ originally came w/your computer?

+"DVD that came with purchase"+
The Leopard System DVD should look like...........

Hi,

Wow. Thanks for writing me.

I had guessed some info and u caught me.

Here are more accurate information:

"(using Previous Folder option to keep files)"
No such option in an archive & install. Do you mean the "preserve user preferences and data" option?
[Sanguito]: The option is called "Archive & Install" with sub-option named "Preserve Users and Network Settings".

"since I had updated Mac OS, it can't be downgraded with version on DVD."
Your system info shows you are still using Mac OS X (10.5). The last Leopard version is 10.5.8 I believe.
Are you positive that you used the System DVD that originally came w/your computer?
[Sanguito]: Oops. My original Mac os x version (factory setup) was 10.5.6. Since i had updated the Mac os x to 10.5.8, when I put DVD with 10.5.6, it said that the "Archive & Install" option is not available. I guess it can only be used when using same or newer version.

Last night, I bravely walked into Apple reseller (I live in vietnam), and picked up Snow Leopard (10.6.3). When I tried to install, it didn't give me option to "Archive & Install", but I just went ahead. It worked. It can start OS.

However, I don't think this was the solution to our problem. If I update to 10.6.4, and this happens again, I would need to buy another MAC os with 10.6.4 or newer version. Any ideas?

Just thought I'd post an update to my white screen/apple logo/spinning wheel issue. Inserting the Snow Leopard Install Disk didn't work (where's the information on the disk as to what's on it?). Anyway, I had success by restoring from Time Machine. OS now works fine and somehow I managed to shave 7 GB off the hard drive--and didn't lose as thing as far as I can tell. This is the first time I've used Time Machine to come to the rescue and I gotta say, it's amazing.
