Mac running slow after installing parallels

The macOS Recovery Environment now opens in the virtual machine. This is the screen that every Mac displays when you hold down Cmd-R at startup. The next screen will offer to install macOS Mojave. Click Continue. On the license agreement screen, click Accept, and then click the Accept button in the pop-up menu. Don't be terrified by the next screen, which offers to install Mojave on a hard disk named Macintosh HD.

This is not your Mac's hard disk, but a virtual hard disk in the virtual machine that Parallels created. Click Macintosh HD and then Continue.

Now wait while Mojave installs itself on the virtual disk. This may take more than a half hour. The virtual Mojave will display the same setup screens that the Mac normally displays when you install an OS. When the installation is complete, you'll see the default Mojave desktop. From your actual Mac's top menu not the topline menu within the virtual machine choose Actions, then Install Parallels Tools.

Follow the prompts to install the Parallels Tools in your virtual Mojave machine, and then restart the virtual machine. Drag your bit applications from your real Mac into the virtual Mojave system. Double-click them to run them. If you're running Mojave and not an earlier version, you'll see the familiar pop-up warning that your bit is not optimized for macOS and will need to be updated. Ignore the warning. Now you can upgrade to Catalina. When the upgrade is complete, start Parallels Desktop and your virtual Mojave machine. In this screenshot, Mojave is running at night, so it's showing the nighttime desktop image, but it's the same virtual machine shown in earlier screens.

Here, I'm running a bit app that won't run in Catalina itself.

parallels 5.0 is running slow.

The bit app appears in its own window on your Mac desktop, and a second top-line menu the menu for the virtual Mac appears beneath the top-line menu of your main macOS installation. As you can see in this window, my Mac is running Catalina, but a bit app is running in a window that looks like any other app window. The virtual machine's dock is visible at the foot of the screen, but it's easy to turn that off from the virtual machine's System Preferences. You can now explore the Parallels options for fine control over your apps and use the System Preferences app in the virtual Mojave to make one or more bit apps start up automatically when the virtual machine is launched.

But what if you've already upgraded to Catalina, or you have a new mac that runs only Catalina, and you can't install Mojave into Parallels with your Mac's recovery partition. All is not lost. Now that Catalina is released, Apple doesn't display an option to download Mojave from the App Store, but it's still on Apple's servers.

If you search deeply enough on Apple's web site, you can find the web address that opens the App Store page where you can download the Mojave installer. I did the search so that you don't have to. Simply visit this Mojave page, and the App Store will offer the Mojave installer for downloading.

New Features

Or, if you prefer to download and install the previous operating system, visit the High Sierra page. Choose the cloud icon to download the installer. Your Mac will ask if you really want to download it; confirm that you do, and wait until it gets downloaded to your Applications folder. Don't run it!

Mac is slow after installing Parallels Desktop

If you have VMware Fusion, you'll need to use the same procedure whether or not you've updated to Catalina. I've asked VMware about this bug, and maybe it will get fixed in a future version.

So, instead of using the Recovery Partition, you'll need to download a Mojave or High Sierra installer, as described above, and drag it into the Select the Installation Window. Follow the prompts to install a virtual machine. After restarting the virtual machine, drag your bit apps into it and run them in the same way you can run them in Parallels. VMware uses the name Unity for the same option that Parallels calls Coherence; it runs an app in a virtual machine in a way that looks as if the program is running in a window of your main macOS installation.

What if you're using a Wine-based app to run a Windows game or app? In almost every case, the Wine-based app won't run in Catalina. This costs money—you have to pay for a copy of Windows—and can be slow and complicated, but it's the only solution right now.

The most prominent vendor of Wine-based software, CodeWeavers, plans to release a Catalina-compatible version, but the job isn't easy and it isn't clear when the new version will arrive. There's one exception to the rule that Wine-based apps won't run in Catalina: If, and only if, you're running bit Wine, and if, and only if, your Windows app is a bit app and one that's simple enough to run under Wine, then Wine can run it in a window under Catalina.

The most effective way I've found to accomplish this is to use the brilliant Wineskin Winery app—an open-source project by a programmer who uses the name doh—in the form of its unofficial update by a programmer who uses the name Gcenx. However, some of these options are timely and take away from other projects you could be working on. It automatically scans, detects, and lets you choose what to delete—all with one click.

No micromanagement to optimize your disk space—Parallels Toolbox does the dirty work for you. The most popular and best hardware upgrade for a solid performance boost is an upgrade to your hard drive and RAM. Before making an expensive purchase and upgrading your hardware and replacing your hard drive or RAM, you can try an additional process by simply resetting your parameter random access memory PRAM.

Because PRAM is used in Macintosh environments with a battery to retain system information, it can be a helpful tip. Note: Intel-based Mac computers also have a system management controller SMC that manages fans, lights, power, and system performance.

You can reset your PRAM with the following steps:. Shut down your Mac. Yes, shut it all the way down. Putting your Mac to sleep or logging out will not work. You will need to hold these keys down in step 4. You must press this key combination before the gray boot screen appears. Continue holding the keys down until the computer restarts and you hear the startup chime for the second time.

Resetting PRAM and SMC may change some system settings such as alarm clock, fans, lights, mouse speed, power actions, startup disk, virtual memory, disk cache, and more preferences. Your computer operating with a lack of RAM is a tricky situation to be in, but it has a relatively easy solution. Think of your RAM like a workbench; the more space you have on your workbench, the more projects you can have out and be actively working on. However, not all RAM is the same. Replacing RAM is as easy as click out, click in, screw on the plate, and boot your Mac to see a difference in everyday performance—but some Mac models cannot be upgraded since the RAM is glued and soldered into place.

While replacing the RAM can be an easy fix, it can also become a costly solution. A solid-state hard drive upgrade can make a huge difference in your everyday experience, regardless of what you may be using your computer for. Benefits of an SSD include better efficiency for energy consumption, more reliable, and quieter operation. Over the last few years, the pricing for SSDs has come down enough to be considered a reasonable investment for an older Mac.

    You can also move your existing hard drive onto an external drive case and use it as a portable drive. However, this is a great opportunity to start fresh, too! Deleting or removing unused applications is quite easy and a quick way to save a ton of space. This will bring up your entire Applications Folder with all applications that are installed on your Mac hard drive. There is one last step: you must empty the Trash to remove the data from your hard drive to free up that disk space.

    Check the Trash to see if there is anything you want to save. Note: When you empty the Trash, the application is permanently removed from your Mac, and you cannot get it back without re-downloading it from an external source such as a website, disk, USB drive, or carrier pigeon. The second tip for speeding up a slow power-up or boot is to turn off any Login Items when you power up your Mac. To do this, follow the steps below:. Note: When you install some applications, they might be automatically added to your Login Items, and they will launch when you start your Mac.
