Hi, I have trouble with my system MacBook Pro 9,1 various OS's - OSX 10.7.5, 10.8.5, 10.9.5 & macOS 10.11.3 being hacked. I've tried formatting the SDD completely and using remote recovery for fresh install. I unplug the wifi&bluetooth contact, all is well. Once I plug the wifi&bluetooth modual back in then my system starts acting compromised with verious indications, happenings or options go missing and system start playing up, it a fight to get the easiest of tasks done. I'm 98% certain there getting in through both wifi&bluetooth,,as I've uninstalled all network devices and deleted the system configurations.plist associated with wifi,,,to eliminate wifi vunrebilities. I'm using Hands Off - firewall,,,without any luck there\its still gaining access to my system. I've tried going to Apple for tech support but it's just a complete inconvenience (3hour drive, the lineup was from the front to the back of the shop) and mostly unhelpful (needing to have the mac for a 2-3weeks). So I up for suggestions. ☝️Please only reply with useful ideas\support... Thanks for your help in advanced Hi, yes all passwords have been changed on many occasions on all devices as a preventative measure, but its still gaining access. Though I did try to check the firmware using this - https://github.com/duo-labs/EFIgy/ And was only presented with inconclusive response. Most of the web sites I try to visit with fixes or tools is a battle,,,I have 2-3 HDD with verious OS which I randomly swap out,, in an attempt to get these fixes\tools downloaded,,,but usually blocked\prevented\stoped or after downloaded it won't unpack cause it corrupted or damaged. This is completely BS, I've had to abandon my system until I gain some help, cause I'm mostly out of answers.
