What are email deliverability records?
DMARC, DKIM, and SPF are email authentication protocols that help protect email senders and recipients from spam, phishing, and other fraudulent activities.
DMARC stands for Domain-based Message Authentication, Reporting, and Conformance. It is a protocol that allows domain owners to specify which mechanisms (DKIM, SPF, or both) are employed for authenticating email messages that they send. DMARC also provides a way for domain owners to receive feedback about the successful or failed delivery of messages that claim to be from their domain.
DKIM stands for DomainKeys Identified Mail. It is a protocol that uses public key cryptography to authenticate the source of an email message. DKIM is typically used to verify that an email message was not altered during transit and that it actually came from the purported sender.
SPF stands for Sender Policy Framework. It is a protocol that allows domain owners to specify which IP addresses are authorized to send email messages on behalf of their domain. SPF is designed to detect and prevent email spoofing, which is a technique used by spammers and phishers to forge the sender's address in an email message.
What do these records actually do?
DMARC, DKIM, and SPF records help protect email senders and recipients from spam, phishing, and other fraudulent activities.
To put it simply, these records verify that an email is actually sent from the domain it claims to be sent from and that it was not tampered with during transit. This helps prevent email spoofing, where spammers and phishers forge the sender's address in an email message.
Domain owners can configure these records in their DNS settings to specify which mechanisms are employed for authenticating email messages. These records help ensure that email messages are legitimate and not fraudulent, which helps protect both the sender and recipient.
How are these records configured?
To configure these records, domain owners must access their DNS (Domain Name System) settings and create the necessary DNS records. For DMARC, a DNS TXT record must be created with the DMARC policy information. For DKIM, a DNS TXT record must be created with the public key information. For SPF, a DNS TXT record must be created with the list of authorized IP addresses. The specific configuration steps may vary depending on the email service provider and DNS hosting service being used.

Hey Everyone, this is a fun one. Apple's 2011 Edition Macbook Pros had this awful underlying fault with the AMD GPU (graphic card) that caused it to fail, and thus your Mac wouldn't boot. It was such a prevalent problem that Apple issued a recall, but in classic Apple fashion they only "fixed" it if you experienced the failure, actually they only replaced the logic board with another having the same underlying GPU fault -- just to buy time to get out of the warranty period. Thanks Apple.
What the problem looks like:
Here's the Fix:
At this point the Mac will restart twice. First, it will run a bunch of text past, this is normal and will only happen once. It will chime and reboot again and run different text past, this is also normal and will happen on every reboot (it's quick). Finally, the Apple logo will appear and the boot will finish. Your mac should work normally now.
If you want to disable the verbose mode (scrolling text at boot) after you've verified the fix is working do this:
You're welcome. If you need help, we charge $25 for the fix, done in 20 minutes. Call or text us.

I came across a really persistent version of weknow.ac malware on a mac. Here's what you need to do to remove it:
Are you getting those annoying Mojave update notifications constantly? Stop them forever.
Hey All. This seems pretty silly. Dropbox's standard installer is an "online" version that simply downloads a very small installer app that when opened, connects to dropbox's server and downloads and installs the full version automatically. This is nice and easy, unless you want to install dropbox on a number of Macs and prefer not to download it over and over again. Fortunately there is an "offline" installer containing the full version of the latest dropbox.
This is the link from dropbox's website which should be up to date (if not let me know in the comments):
Enjoy. You're Welcome.
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.

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 wary, 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.
if you've goofed around and tried to change your user name though the advanced settings in your mac, you may have ended up with your user switching back to a standard account. if you only started with one account, then you've left yourself with no admin account. Aaaand you can't change anything. Here's is what you do:
Here's a quick one.
The Situation: you have a million screenshots on your desktop. You curse mess and want to take control. Great! Set a folder to keep all the screenshots automatically, rather than turning your desktop into unwieldy monster.
That's it! Now when you take a screenshot it will be saved to the folder you created rather than the desktop. You've tamed the beast. Pat yourself on the back. You're welcome.
This one is quick. You're running Sierra and you've downloaded an app from the web, but when you try to open it you get an error that says "appname.app is damaged and cannot be opened..." Sierra gatekeeper security is strict, but there is an easy way to enable non-certified apps to open.
**proceed at your own risk, apps that the system doesn't want to open could be malicious**
to re-enable the security follow the same steps but instead enter: sudo spctl --master-enable
