What Does It Mean That “App” Is Not Optimized For Your Mac?

If you are a MacOS user, you most likely have a pop up message on your mac recently stating, “This app will not work with future versions of macOS and needs to be updated to improve compatibility. Contact the developer for more information.

Pop up you get whenever you run an app that’s not 64-bit on your Mac.

Despite the fact that the frequency of those messages is a bit exasperating, you need to pay attention to the issue they raise.

Apple is switching to an all 64-bit platform starting with macOS Catalina. All applications that are of the 32-bit kind will not be compatible with Apple’s operating system past the macOS Mojave (Version 10.14)

Is There Anything I Need To Do About Mac OS Transition To 64-bit Only OS?

It is imperative that you make sure your essential applications are compatible with future versions of macOS. Applications like your word processor, your code editor, your remote desktop application, your virtual machine platform are only a few examples you need to verify they are compatible.

If you use your Mac for making, producing, editing, and potentially even playing music, this is a very important notification for you. Please make sure your application is 64-bit compatible or do not upgrade to any macOS past Mojave until your applications are 64-bit ready. Pro-Tools-Experts suggests a list of press releases and announcements from music application vendors and producers warning their users not to upgrade to macOS Catalina just yet.

How Do I Find Out Which Applications Are 32-bit or 64-bit On My Mac?

The process is quite easy to find out which applications on your Mac are 32-bit or 64-bit. In a helpful guide, Apple suggests:

  • From the Apple menu, choose About This Mac,
  • then click the System Report button.
  • From the system report, scroll down to Software in the sidebar,
  • then select Applications.
  • When you select an individual application, you will see a field titled 64-bit (Intel). “Yes” indicates 64-bit; “No” indicates 32-bit.

If you’re using macOS Mojave, select Legacy Software in the sidebar to see all applications that have not been updated to use 64-bit processes.

We hope that you will now prepare for the new all 64-bit era with more confidence! Please ask us directly if any questions on Twitter @RafikiTechno or directly on this blog through our contact form.

How to Share Folder as Time Machine Backup Destination in macOS High Sierra version 10.13.1

If you were using OS X Server in macOS Sierra then upgraded to macOS High Sierra, you are probably wondering what in the world happened to the Time Machine Option in OS X Server. A good discussion is going on about the question here, but we do have a solution for you:

As it turns out that Apple decided that Time Machine sharing will now become a part of macOS instead of Server 5.4. You can now used a shared Folder as a Time Machine backup destination using the Sharing preferences in your macOS System Preferences.

According to the Mac Help instructions, to Set up a shared Time Machine backup folder,

  1. Choose Apple menu > System Preferences, then click Sharing.
  2. Select the File Sharing checkbox.
  3. Click the Add button + at the bottom of the Shared Folders list.
  4. Navigate to and select the folder you want to use for sharing, then click Add.
  5. Select the name of the shared folder, click Options, then make sure “Share files and folders using SMB” is selected and “Share files and folders using AFP” is not selected.
  6. Control-click the name of the folder, then choose Advanced Options.
  7. Select “Share as a Time Machine backup destination.”
  8. If desired, select “Limit backups to,” then enter a size.
  9. Click OK.

The question remains, though, of how do you know your remote devices are currently being backed up or how much of their backup has been done and how much is left?

Macbook Won’t Boot Past Gray Screen With Apple Logo

You probably just want to jump straight to the solution. So, here it is:

  1. Unplug all peripheral devices from your computer.
  2. While holding Option + Command + R + P, Power Up the computer, listen for 1st chime, then 2nd chime, then immediately release all the keys you were holding and watch the computer come to life.*
  3. Proceed to backing up your data onto an external hard drive or other solution you have at hand for backup and remember to backup on a regular basis.
  4. You are good to go!

Now, What Does Command + Option + R + P Do?

Glad you asked! I did not know either. But I looked  That key combination helps reset the NVRAM, sometimes called PRAM, on your Mac. The PRAM is a type of Non-Volatile RAM on your computer that stores some important parameters about your computer’s peripheral devices. This is why you are to unplug all peripheral devices as a first step of this troubleshooting.

According to Apple, “If you experience issues with sleep, wake, power, charging your Mac notebook battery, or other power-related symptoms, you might need to reset the SMC (System Management Controller),” which involves a different set of keys.

Lessons Learned From This Case of Mac Troubleshooting

Lesson Numero Uno: Always backup your computers! It is an investment worth it considering that most external hard drives cost way less than the price of a brand new computer. So, get on the Internet and look up best ways to backup your type of computer and go ahead and do it. You can also just ask your trusted and proven tech-savvy rafiki (translate “friend”) how it is done.

Finally, I want to mention that, as you would quickly notice by glancing on the keyboard nearest to you, the key combination that brings your Mac back to life requires some dexterity you could get from some practice with a keyboard or piano. So, lesson learned, find a piano class and start the lessons as soon as you can.
