Hi All,

My iMac (2011 mid ) high serria stuck in Apple loading bar in 100% progress. It cannot log into login menu.

I did :
1. Cannot enter recovery and cannot enter disk utility by cmd+r
2. Can enter internet recovery but also stuck after download from internet completed.
3. Reset SMC
4. RESET PRAM...cmd+option+p+r .
5. CREATE USB BOOTABLE DRIVE AND PRESS (OPTION KEY ) TO SELECT USB DRIVE but stuck in Apple loading bar again.


Then, I use cmd+v to verbose mode and see the log with screenshot provided.

Friends, what can I further do ?

Thanks....

A bad battery can cause all sorts of problems. A missing battery is actually better—your settings aren’t saved but won’t cause the problems a bad battery can. If you know how to do it, get a CR2032 and pop it in.

Do I think it’s the real problem? No but it could be. I’ve seen this before.

Other possibilities include bad RAM. Pull 2 sticks. If that doesn’t do it, replace them and pull the other 2. You might get lucky.

Otherwise, 2011 27” iMacs can often be found in the $200–500 range on eBay.

My advice:

For the moment, forget about installing onto the internal drive.

Instead, get either an external drive or an external USB flashdrive 32gb (or larger).

Use Disk Utility to format it to Mac OS extended with journaling enabled.

Now, open the OS installer, "aim at" at the EXTERNAL drive, and see if the installer will install a copy of the OS -there-, instead.

Does this work?

I think it's not the battery problem because i can enter the single-mode (cmd+s) and check the system date. it's correct.[see screenshot]...
