- Mac Is Running Slow
However, I noticed something: the Mac App Store was terribly slow, unusually unresponsive when compared to the same Mac App Store running on my 2008 MacBook Pro and 2009 iMac. I asked on Twitter, and lots of people seemed to share my frustrations with “beachballs”, slow loading times, and general bugginess of the program. Office 365 apps very slow to open on iMac I am running the most-up-to-date version of office 365 on the current version of Mac OS High Sierra (v10.13.5) on my late 2015 iMac Opening any of the Office 365 apps takes anything between 30 and 60 secs. The problem is that it takes like 20-30 seconds to even open Firefox (after restart). Even clicking on 'About this Mac' takes like 20 seconds. I have to mention: I received this MacBook and it was cleaned. No chaches and stuff, no apps installed. It was slow from day 1. I opened the back cover, cleaned it. Did not change thermal paste though.
The safest place to get apps for your Mac is the App Store. Apple reviews each app in the App Store before it’s accepted and signs it to ensure that it hasn’t been tampered with or altered. If there’s ever a problem with an app, Apple can quickly remove it from the store.
If you download and install apps from the internet or directly from a developer, macOS continues to protect your Mac. When you install Mac apps, plug-ins, and installer packages from outside the App Store, macOS checks the Developer ID signature to verify that the software is from an identified developer and that it has not been altered. By default, macOS Catalina also requires software to be notarized, so you can be confident that the software you run on your Mac doesn't contain known malware. Before opening downloaded software for the first time, macOS requests your approval to make sure you aren’t misled into running software you didn’t expect.
Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy.
View the app security settings on your Mac
By default, the security and privacy preferences of your Mac are set to allow apps from the App Store and identified developers. For additional security, you can chose to allow only apps from the App Store.
In System Preferences, click Security & Privacy, then click General. Click the lock and enter your password to make changes. Select App Store under the header “Allow apps downloaded from.”
Open a developer-signed or notarized app
If your Mac is set to allow apps from the App Store and identified developers, the first time that you launch a new app, your Mac asks if you’re sure you want to open it.
An app that has been notarized by Apple indicates that Apple checked it for malicious software and none was detected:
Prior to macOS Catalina, opening an app that hasn't been notarized shows a yellow warning icon and asks if you're sure you want to open it:
If you see a warning message and can’t install an app
If you have set your Mac to allow apps only from the App Store and you try to install an app from elsewhere, your Mac will say that the app can't be opened because it was not downloaded from the App Store.*
If your Mac is set to allow apps from the App Store and identified developers, and you try to install an app that isn’t signed by an identified developer or—in macOS Catalina—notarized by Apple, you also see a warning that the app cannot be opened.
If you see this warning, it means that the app was not notarized, and Apple could not scan the app for known malicious software.
See all open apps mac. You may want to look for an updated version of the app in the App Store or look for an alternative app.
If macOS detects a malicious app
If macOS detects that an app has malicious content, it will notify you when you try to open it and ask you to move it to the Trash.
How to open an app that hasn’t been notarized or is from an unidentified developer
Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy. If you’re certain that an app you want to install is from a trustworthy source and hasn’t been tampered with, you can temporarily override your Mac security settings to open it.
In macOS Catalina and macOS Mojave, when an app fails to install because it hasn’t been notarized or is from an unidentified developer, it will appear in System Preferences > Security & Privacy, under the General tab. Click Open Anyway to confirm your intent to open or install the app.
The warning prompt reappears, and you can click Open.*

The app is now saved as an exception to your security settings, and you can open it in the future by double-clicking it, just as you can any authorized app.
*If you're prompted to open Finder: control-click the app in Finder, choose Open from the menu, and then click Open in the dialog that appears. Enter your admin name and password to open the app.
A Mac usually takes care of itself. But once its been used for one too many years, it starts getting slow, just like any computer. It can be anything; hard drive overload, corrupted system files, a rogue app or just an outdated OS. There could be a lot wrong under the hood, and hunting for the specific culprit on your own takes a long time.
Fortunately, Mac has a slew of built-in and third party diagnostic and cleaning utilities to help you speed the Mac right up. Check out the apps/tips listed below.

1. Onyx
Onyx is one of the best maintenance tools for Mac. It opens up hidden system settings that go well beyond Mac’s System Preferences. It lets you clean the system or user cache, deleting old internet files, system cache, user elements and more in the process.
The app has a one-click maintenance mode for beginners. Use the default settings if you don’t know what you’re doing. Also, keep in mind that Onyx is like a vacuum cleaner and not a sweeper. Using it everyday might actually harm your system. So use it once a month and your Mac will stay fresh.
Check out our in-depth guide on Onyx to get the most out of the app.
2. Resetting PRAM and SRC
I’ve previously written about PRAM, SRC, and what they do in detail. I’ve also showed you how to reset them.
Resetting your PRAM is quite easy and it’s like clearing the cache, only for your entire OS. Resetting the PRAM resets the internal settings of the OS back to the defaults. This means if any rogue app messed something up, resetting PRAM can solve it.
How To Reset PRAM
Step 1: Turn off your Mac. No need to remove the battery or detach the power chord.
Step 2: Turn on your Mac and hold down the Command+Option+P+R keys, all at the same time.
Step 3: Hold down all four keys until you hear the startup sound twice.
A couple of months ago when OS X Mavericks on my system used to hang for a couple of seconds for no apparent reason, resetting the PRAM did the trick.

3. Yasu
Onyx is a great app to keep things working smoothly. Yasu is the app to download when your Mac is giving you weird problems. The app is really easy to use and not nearly as overwhelming as Onyx (but also isn’t as feature rich).
Yasu resets permissions, runs cron scripts, and clears cache and log all from one screen. Check what you want to do, click OK and you’re done.
4. More Suggestions
Activity Monitor: Mac’s built-in Activity Monitor is pretty robust. If your Mac is suddenly behaving oddly, open the app and see what’s taking up the most CPU or RAM. If there is a rogue app, it will be on top of the list. Remove and/or reinstall the app to see if it works.
Switch to SSD: While the apps listed here will give a kick to your aging Mac, nothing can help the slow-spinning hard drive. The best way to give an old Mac a speed boost is by switching to an SSD. If you have a non-Retina MacBook, the process is pretty easy.
Update OS X: Unlike with Windows, OS X works better on every MacBook, even older ones, with updates. I’ve seen this happen when I updated to Mavericks from Mountain Lion and surprisingly again when I went to Yosemite beta.
