OK, here some of the common problems I’ve had with MacOS:
- MacOS Sierra seems to have developed this, when copying (but not moving) files on a Synology NAS, I get the dreaded
Can't move files, the required files cannot be found. Error code -43
- When you try to delete in the Trash, you get the same error.
- When you are on your network and connect to a Network drive, it gives a drive not found message.
- The file is in use when you are trying to copy on a network drive.
The problem to each of these appears to be to kill Option Right click on Finder and choose Relaunch or kill it from the Activity Monitor with a force quit or logout and back and it should work again.
I always have trouble the first time I try to pair my Mac bluetooth keyboards. Here’s a quick guide to what you have to do:
- Most of the time the device isn’t visible. You should check the single LED light. If it is fast blinking, then the keyboard or mouse is not paired and you should be able to see it
- To actually see it, you need to go to System Preferences/Bluetooth and wait for it to appear. Many times it just doesn’t appear no matter what I do.
- One problem is that the keyboard only pairs with one particular device. For me, I forget which keyboard goes to which computers so you need to reset the keyboard so that it pairs. The way to tell is if you get a slow blink rate rather than fast. Here’s how to reset one. Take the batteries out (this only works for the older keyboards obviously, not the new ones with the embedded battery). This resets it. Then put the batteries back in and hold down the power button. Don’t let it go. You will see the LED go solid then go to fast blink. You should now see it in the Bluetooth menu.
- If you do then try to pair if it says “Pairing failed” or doesn’t connect, then you should try to turn the Bluetooth on and off on the Mac. Sometimes, the bluetooth driver stack gets hung.
Ok we did find a loose m.2 SSD in our system. The reason is that some motherboards do not come with the proper screw to tighten down. After much googling, it looks like this tiny screw is an M2 3mm screw. These are about $10 for 300 on Amazon 🙂
OK we have three PCs down and are working our way through it. If you really have a hard problem, here are the steps:
- Buy a test chassis system. This is something that is case-less and let’s you swap components easily. It is really useful when something goes wrong.
- Here are the steps, first put in the motherboard and the power supply. Power up the device and make sure the motherboard lights up and the power supply spins. You will need a small button to jumper across the power pins.
- If this works, then put in the processor (you do not need a fan yet) and plug in a monitor and see if you get the POST. This will tell you the processor is alive
In our case, our CPU failed this test. We did find a loose m.2 SSD and it probably shorted out the motherboard.
Well it might be better to wait until after Christmas, but here are some things to get:
- $100 iTunes Gift card is $85 on eBay. That’s quite a deal from PayPal no less.
OK the world is a little confusing right now, but with a 4K cable, you need a 18Gbps at least to make sure you get 4Kp60:
- Monoprice Certified Premium High Speed Cables. These are just $5 for a 3 foot length
A buddy asked what’s a decent gaming PC. This is a great time to buy one as the nVidia GTX-1080s are coming down in price and UHD is coming out, so Techradar had a good overview http://www.techradar.com/news/computing/pc/10-of-the-best-gaming-pcs-you-can-buy-in-2015-1304263:
- Alienware Aurora F5. $800. This is Dell’s premium line. It is tiny min ITX and very fast with a GTX1080. Nice looking and from Dell.
- Lenovo Ideacentre Y900, this is Lenovo and a decent one too. It’s a little expensive compared with the Alienware.

There are other specialty brands too although building one yourself is really the funnest option!
