Alex wants to upgrade his mac and attach it to a MIDI keyboard to make music. He wants to be able to tether it, not rely on a network or wifi connection. Leo says that MacOS doesn't support touch, so you'd have to use a simulated mouse. But it's doable. Leo would recommend going with a Thunderbolt connection in order to do it. The chatroom says that there's a Mac Compatible touchscreen Monitor on sale at Amazon.
Spenser has an old white MacBook that he uses to tether to his Nikon cameras and take pictures of his astronomy. There's a solar eclipse coming in 2024, and he wants to know if he can use it even though it's over 10 years old now. Leo says it may be better to see if there's a new version of the software used on a newer Mac. Unfortunately, the old version of the software won't work on modern macs because Apple stopped supporting 32-bit applications. So you'd need a newer version of the software.
Angela has a 2015 Mac and when she shuts it down, it turns back on. Leo says it's an incomplete shutdown, with some app hanging it up. A wipe and reinstall of the OS should make it go away. Make sure you backup your data first.
You can launch the activity monitor and it'll show you all the processes that are running.
Mark wants to know if he can check out Linux on his iMac. Leo says in theory, yes. But Leo's experience is that they don't really work hand in hand well. Do some research online to see which version of Linux works best on a Mac. Then put that version on a USB key, then boot the mac holding down the command key. That'll give you a list of drives to access, and then you can run Linux on the USB key to see if it works.
Kris wants to get a new hard drive for his Mac. Leo says to get a 512GB hard drive that will house the OS and programs, and then an external drive for data. Going with a Thunderbolt 3 will make it faster than the internal drive.
Ananias got a bunch of Macs with Quadros and wants to know if they're worth anything. Leo says he can go to EveryMac.com to see their history. But they run a PowerPC chip, and as such, aren't really supported in the modern computing world. Likely, they just fodder for eCycling. However, it is still worth checking out eBay to see if there are any opportunities.
Shane works for the Schlage lock company and more people want the company to start using Macs. Leo says that volume licensing is not as complicated as microsoft, but Apple also doesn't have as good of enterprise level support either. But Apple will update the computer regularly. He doesn't have to install the updates — He could defer or even ignore them. It's not a good idea, though.
If you have an old user account on your Mac that you can no longer access, there's a way you can still get into it as long as you have an "Administrator" account on that Mac. Just get into the System Preferences from the Apple Menu and click "Users & Groups". Then click the lock icon and enter the admin name and password. Select a user, and then click "Reset Password".
Gina's iMac keyboard isn't very comfortable. Where can she get a new one? Jason recommends going over to thewirecutter.com and search for "Keyboards." Her Mac can use any keyboard out there, and in the System Preferences there's also an option to swap the Command and Option keys for those who need that preference.
Randy has been bit by malware and it won't disappear. Leo says Randy needs to just start over. He should just backup his data, then restart his computer, hold CMD + R, erase the hard drive and reinstall. He should get his data backed up first, though. It's really the safest way to fix his problem.
