[QUOTE="GeoFan49, post: 1551947, member: 314949"] Any troubleshooting suggestions? After upgrading my MacBook Pro (mid-2009, 15-inch) with 8GB RAM for $82, and 1TB internal drive 7200 RPM for $98, and replaced one damaged keycap for $7, it runs a lot peppier now. Feels almost like a new machine. Looking at a new battery... $120. for A1321, 77.5-73wh. [U][B]What I did:[/B][/U] Installed 8GB RAM, ran memtest, five passes overnight, after changing the RAM, and it found no errors. Installed new internal hard drive, formatted and installed OS X 10.6.8 from flash drive. Restored from Time Machine backup; the boot drive name was "Mac750GB" which I renamed to "Mac1TB" on a whim. The Finder has been running at 70-90% CPU for many, many days now. I have rebooted once every few days. I am guessing that the Finder is rebuilding the Spotlight index for the boot drive, because I had renamed it. However, there is another anomaly, which causes problems. [B][U]What happens now:[/U][/B] [SIZE="4"][B]Every 20-30 minutes the entire system hangs for about 30 seconds. [/B][/SIZE][B][/B] The mouse pointer continues to move, but the menu bar clock FREESES (no flashing ":" and no seconds counting) for thirty seconds. Typing ceases, the keyboard is frozen, and mouse clicks usually cause a SBBOD (Beachball.) Any ideas what is going on with these freezes? Could it have anything to do with the Finder 90% CPU for days? How to troubleshoot this? Should I just be patient and let the Finder run for a few more days? Mac OS X 10.6.8 (getting ready to update to Mavericks when the system is stable.) Macbook Pro Core2Duo Mid-2009 2.53GHz MC118LL/A 15.4 inch, MacBookPro5,4. Activity Monitor screenshots attached.
