Hi guys, I'd really appreciate any help anyone can give. I've tried every trick I can think of within my current technical competancy and I'm stumped for what to try next. Apologies for the large message, I've tried to list everything relevant I can think of to help show the problems.

Historical Issues

Lately I've had some odd behaivour with it that may or may not be related or even significant...

  • Finder hanging semi-regularly.
  • Different programs preventing shut down.
  • My volume randomly going up and down like the keys are being pushed (possibly

a remote issue related to my recently purchased Apple TV, though not actually being used at the time of incendents?)


Current Issues

Suddenly this week it feels like everything's causing trouble. Issues inclue...

  • Various programs crashing or hanging (Firefox, Finder, Photoshop, Illustrator etc. - seems non-specific). Finder in particular I can't even get to reboot sometimes.
  • Finder sometimes not loading view of files in folders, no spinning loading wheel either.
  • Power cable light went amber for a period yesterday even though the MBP was at full power and plugged in all day.
  • Photoshop file I created and know was working fine yesterday suddenly had an 'unexpected end-of-file error' today suggesting it wasn't saved properly and is since corrupted.
  • Everything is running painfully slow, even when it works.


Things I've changed lately

The only things I can think of that I've done differently lately are these...

  • Upgraded my Dropbox to 100gb and started working with large artwork files directly from there.
  • Changed the settings on my Airport Express Base Station at my office, which my MBP is set to try and connect to when possible.


Remedies I've tried

  • Rebooting numerous times.
  • Zapping the P-ram, which wont even work at the moment. Even with holding in the power button the MBP just loads to the login screen as per usual.
  • Rebooting in safe mode.
  • Emptying the trash can.
  • Running iAntivirus to scan for viruses which came up clear.
  • Repaired Disk and Repaired Disk Permissions.
  • Run Spring Cleaning to clean System Caches.
  • Cleared more space on my hard drive.
  • Updated all software


I'm completley out of ideas and I'm still none the wiser as to what the actual issue is. Is it just a matter of buying a wad more memory to juice it up more or is there something else I'm missing?


Thanks again for any help anyone can give, I'm really desperate at this point....



MacBook Pro, Mac OS X (10.7.3)

    Try to download Ccleaner from the App Store.

    Anytime. And yes, that should speed it up as well.

    I have almost the same problem, same type of machine, up to 8 GB of RAM and with almost 70 GB of free space on a 500 GB HD (14% free) and it crashed and never came back to run OS X Lion after I tried to record my first project in iDVD. I have already tested HD with the Utility System but it did not identify any problems with the HD (SMART status: verified, OK). Since I reset the PRAM of the equipment, went back to the memory banks of 4 GB original equipment and even trying (could not) re-install OS X Lion, the machine remains extremely slow. I've tried to recover the old system (using Time-Machine backup files) and although the process last for hours (3 hours or more), it did not work and results with a machine without operational system. It would be a problem (very strange) with the original HD machine (a Hitachi) or an hardware problem? Anyone else been through this? My macbook pro is mid 2012, with the first generation of i7 processor. And currently is complicated (pratically impossible), try to use the machine even with Snow Leopard 10.6.3. It performs very and oddly slow. Strange too, I can not upgrade to Snow Leopard 10.6.8 (such to access the App Store). The update process fails at the end and the update is not installed. I've tried more than once and not updated. Finally I ran the Apple hardware testing program pressing the D key at start-up of the machine with the Snow Leopard DVD installation and the testing hangs after about 20 minutes running. Unfortunately, as Apple's systems provide few text messages, I did not know what it is, where is the problem. It would be a problem of manufacturing defect? Could someone suggest me something else to do? Thanks in advance.
