Hello everyone. Im starting to worry about my iMacs health. It has less than a year and is starting to show really weird behaviours, being the main symptom a sudden mouse lag (like if when moving the pointer it looks like if jumping frames) that get worse to worst until it freezes the entire system being the restart as the first sight of it the only solution. i thought this may be because the bluetooth mouse and stuff but no, it still happens with a cord mouse and the last time i try i saw it affect keyboard and other system abilities. I check the activity monitor and it was no stressful process running (less than 5% of cpu used) and around 7Gb of free ram. I check on the console expecting redundant issues or anything that could cause this kind of slow down but the console show everything fine, don't know whats going on. This same mac suffer from a bug generated by apple software update months ago that locked the /tmp file on the system roots, leaving me no choice than deactivate SIP More detailed info of that issue here http://forums.macrumors.com/threads/coretelephony-trace-file-error.2004389/ Thanks in advance for anyone that could give me a hand on this issue.
