I've recently gotten around to updating to OS X El Capitan and I've encountered an unanticipated problem. I've been using custom Icons for apps and folders for ages now, and apparently I can't edit the icons of some essential applications without disabling SIP. To do this, however, it seems I have to use Recovery mode, which turns out to be a bit of a problem. I'm not sure how or why, but I can't seem to access the Recovery Partition. I know it exists, I can see it with "diskutil list". I can't access it by holding either CMD+R or CMD+ALT at start-up, though. I'm using a mid-2009 Macbook Pro, so I can't access the online Recovery Mode. I've had my DVD drive replaced with SSD a while ago, and I think the Recovery Partition may have gotten disabled or something as part of the associated back-up. I've tried creating a new recovery partition using a specific app (Recovery Partition Creator), with no success. I've tried turning a USB drive into a Recovery Disk, but when trying to boot from it it just boots like usual for some reason I can't begin to fathom. I don't know what else to do, and searching the web seems to yield no solutions. So what I'm basically looking for is either a way to disable SIP without Recovery Mode or a way of accessing Recovery Mode. I've been trying things for the last few hours, and I'm at a loss. I'm not sure I can go back to the regular icons, especially considering most of my folders and apps still have custom icons. I honestly don't recognise half of what my apps are supposed to be and it's frustrating me to no end. Any help would be greatly appreciated.
