iMac Retina 5K and hard disk defragmentation

Good day!
There are two questions that baffle me.
Do I need to defragment my hard drive? I use Photoshop very actively,as well as Final Cut Pro. Due to the constant movement of huge files, any disks start to work slower over time. On Windows, defragmentation is easy to do and it gives a positive effect,but will it give the same positive effect on OS X? A friend advised using the ''Drive Genius''
program ,since Apple's technical staff uses the utility to work with problematic hardware.

And the second question about Mac mini: how do I remove the numbers in the red circle from the App Store update? Already annoying. The options "remove the icon in the App Store from the dock \mailtab from disk\upgrade to an older OS version" are not considered. I use the mountain lion OS


I use two computers:
1. iMac Retina 5K (OS Catalina 10.15.7), 64 GB RAM ,Radeon Pro 5500XT (8 GB)
2. Mac Mini 2012 (OS Mountain Lion 10.8.3), SSD+HDD,16 GB RAM
thank you in advance to all who responded :)

The good news is that on a Mac you do not need to defrag your disk as your Mac optimises your files in the background. In any case if you have a SSD then you should definitely not run a defrag utility as you may reduce its lifespan.

You DO need to defrag platter-based drives now and then, regardless of what Apple says.
This is particularly true for audio/video production where large segments of "free, contiguous space" may be required.

The best Mac app to do this was named "iDefrag", by the now-closed Coriolis Systems:

However, they have made their old apps freely downloadable.
So you can still find iDefrag -- now free to use -- at the URL above.

I suggest you give it a try -- it's very good software for its time.

Thank you very much! I didn't know that you can't defragment an SSD. It is good that I have never performed this procedure. The more the SSD service life is reduced.

Oh,Thank you, I was already depressed,because the program my friends called costs money and it's not known if it's good or a placebo program.
I haven't even heard of defragmentation. Thank you,I will definitely try!
Now the second question remains-How do I remove numbers with update notifications from the App Store label? Can there be commands via the terminal or applications?

I understand what @Fishrrman is saying, however unless your hard disk has little space left (less than 10% as since 10.2 Mac OS will defrag in the background provided you have more than 10% available) you are unlikely to see much benefit, in addition if you are using Apple's new file system from High Sierra onwards - APFS then you will not be able to defrag your disk.

I have been video editing on a Mac since 2002 and I have never had to defrag my disk.

I usually leave the HDD filled to 70%,unless of course I use the HDD as a temporary place to store heavy files ,then the HDD turns out to score almost to the eyeballs by 90%. However, the system slows down mercilessly.

Have you ever experienced a speed drop due to the new SSD firmware?

I tend to use my internal SSD for live projects and then transfer when complete to an external drive. I have never had any problems with Firmware updates impacting SSD performance.

Please help me solve this problem.
Maybe there are commands via the terminal or software that allows you to remove the update notification from the AppStore and annoying numbers in the red circle? Googling doesn't help

If you want to disable Red Badge Update Icon this should work.

1.Launch the Terminal application

2. Enter the following syntax exactly at the command line:

defaults write com.apple.systempreferences AttentionPrefBundleIDs 0 && killall Dock

3. Hit return, the Dock will refresh automatically and the System Preferences icon will no longer show the red updates badge

If you want to re-enable then use the following in step 2 above.

defaults write com.apple.systempreferences AttentionPrefBundleIDs 1 && killall Dock

Yes,I want to disable them and make them not displayed. Thank You very much! Now on the road, I'll come and enter the command! :) Thank You!

WAIT!
STOP RIGHT THERE!

I said defragging was for PLATTER-BASED hard drives, not SSDs.

One can "defrag" an SSD, but it won't make it any faster.
Doing so will "increase the wear" on it.
That's why it's probably best to -not- "defrag" an SSD.

Ah... now it's all clear. Thanks! :)
