![]() ![]() If you don’t have an Apple router, you may need to instead go into your router settings and try changing the channel manually. Specifically, a different channel than the one your Bluetooth devices is using to communicate. Upon restart, the station will search for a new channel. That means no brick walls between you and your devices, and definitely no metal desks!Ģ.) Change Router Channel: If you have an Apple router and you’re constantly getting interference with your WiFi, try rebooting it. So if you’re really struggling with interference, your first step should be to move your Bluetooth devices away from these materials. Metal, bulletproof glass, concrete, and plaster are particularly bad, and marble, plaster, and brick aren’t great easy. Let's try the below steps to see if that helps -ġ.) Remove All Barriers: Certain building materials can get in the way of weaker signals like Bluetooth. I understand that you are unable to communicate to your printer from your mac os.

So.if I reinstall Yosemite onto my main HDD, either as an in-place, or a fresh, I don't have much confidence at this point that a. I installed Mavericks onto VM Ware (my VM Ware version doesn't support Yosemite - but how different can the layout of the recovery partitions in 10.9 and 10.10 be?). So.I installed Yosemite onto an external USB drive. The aforementioned //.diagnostics folder, within the recovery partition, made visible by terminal commands to make all partitions visible, invisible files visible, etc. So, I thought I found a clue as to the location of Apple Diagnostics (as opposed to AHT), over at Stack Exchange. I'd love to find an answer that doesn't involve either my reinstalling Yosemite or having to schlep this thing to an Apple store, if possible. Trying to get into Apple Diagnostics after all this yielded the same result as before. The fan runs harder, so I assume something is making the CPU work harder, but I have no idea what.ĥ) I then tried doing all the other checks / fixes I could think of - resetting PRAM and SMC, booting into the repair partition and running volume checks and permissions repair on my boot volume, and booting into safe mode, followed by a restart. No diagnostic option button appears at the bottom, the screen doesn't change. Choosing English places a check-mark next to the selection, but then nothing else happens. ![]() This may take a while." screen, which runs for less than a minute, then sends me to a language selection screen, with "power down" and "restart" selections at the bottom. So, pushing D immediately after pushing the power button takes me to a "Starting Internet Recovery. This caused me to try running Apple Diagnostics. That went uneventfully.ģ) I have successfully, several times, run Apple Diagnostics ("D" on startup) in the past, and now can't remember if the last time I did so was under Mavericks, or if I'd ever done it under Yosemite.Ĥ) Lately have noticed my machine "double rebooting" - meaning that when I reboot, I hear a start-up chime twice, and then it goes through the remainder of the boot normally. Hoping someone has an idea of what's going on with my machine.ġ) I have a late 2013 retina MBP, came loaded with Mavericks as I recall.Ģ) Did a clean-install upgrade to Yosemite shortly after the OS came out (off of a USB drive). ![]()
