If you have to copy a large amount of data, say 15TB from one hard drive to another, the finder is not your friend. The way the finder copies data allows for disk errors or I/O (in/out) errors to fail the whole copy. For example, if you've been running that 15TB copy for a few days and it fails with an error at 99%, you're screwed. Using the terminal to run an rsync command is ideal, it copies files bit by bit, safely, and if there is a problem (disk disconnected? power outage?) run it again and it'll start off where it left off. Sweet.
*If the copy is interrupted for any reason, run the same command again.

The most persistent malware we've seen is the Smart Search weknow.ac. This malware has the usual launch agent, browser extension, install files, but this one also changes the chrome profile. This is some pretty serious stuff that get's deep at the heart of Google Chrome, so even when you remove the files, the malware search page persists. Don't worry! We'll fix this together.
How do you know if you have this particular Malware:
Remove is pretty simple. Go screw yourselves malware jerks. Here's what you do:

Apple has upgraded some security features in macOS starting with Sierra. Sometimes when you install an app that needs an extension to run it prompts you to open Security and Privacy preference and click the "Allow" button. BUT, apple has restricted that click to a physical click of the trackpad or mouse, so what if you're remoting into the Mac?
Here's the fix:
Sometimes you want to install some app from the internet, and your Mac gives you an error that says something like "can't be opened because it's from an unidentified developer" or "...is damaged and can't be opened. You should move it to the Trash."
Well if you trust the app, and want to install it anyways. Just disable macOS Gatekeeper.
Re-enable gatekeeper with: sudo spctl --master-enable
Apple Mail has been a finicky bit of software since its inception. Some love it, some hate it. One problem we've seen recently in V10 with High Sierra is that emails display [the usually] hidden HTML code. This can be frustrating. Some have 'solved' it using Apple Mail's built-in "rebuild" option, but the problem seems to return pretty quick. Here's how you can solve this issue and other weird mail issues too.
The java on your mac can easily become outdated. Apple doesn't love java, so the auto tools to "update" it often don't work. Here's how you can check which version you're currently on, and how to remove it.
Note: the current version of Java JDK is V10. (8/23/18) found here.
Check the current version:
I like the stable Java Version 8. Found here.
Super fast one. You lost your notes in the notes app. You have a backup (hopefully), here's where you go to retrieve them:
Simply copy the folder "group.com.apple.notes" from your backup to the same location on your Mac.
Boom, notes are back.
Sometimes Dropbox wont install/load if there was a previous version installed, or if you changed the name of the home folder on your Mac. Get it up and running again.
Maybe you wanna start using 1password or lastpass, but you have all your passwords saved in google chrome. Export them, duh, it's easy.
A CSV file will be downloaded that contains all your passwords. You can import that to most password applications.
DON'T LET ANYONE GET YOUR PASSWORD CSV FILE. DELETE IT ASAP.
There are lots of long blogs about how to do this. Some are written for the beta version of High Sierra and are wrong. Here's the quick and dirty on trashing your APFS disk in High Sierra and go back to HFS.
APFS is brand new disk partition type that Apple introduced in High Sierra. Although it has some benefits, I don't care for it. Anything that apple releases that is brand new, be weary, there are usually issues with it. Also, if you're a mac tech reading this, upgrading OSes or converting from HFS to APFS to solve performance problems is not a solution. If you need help understanding why, email me.
***WARNING: THIS WILL DELETE THE CONTENTS OF YOUR HARD DRIVE. MAKE A BACKUP***
That's it. You can now re-install, re-store, re-image to your HFS disk however you like. You're welcome.
