Mac Downloading Slow

Gone are the days when you could make yourself a sandwich while a web page was loading. The Internet is lightning fast now, so when things get slow as you browse the web it feels.. unnatural.

Safari is not the fastest of browsers to begin with, and it can get downright sluggish as time goes by. There are several possible reasons for Safari running slow or freezing, and in this post we’ll see what they are and what can be done about them. The fixes below are done manually, but to streamline the process get a utility like CleanMyMac X. It’s perfect for fixing a slow Safari on Mac, and it’s free to download.

Safari running slow on Mac - How to speed it up

So, why is Safari so slow? It could be..

Since High Sierra 10.13.2 and now 10.13.3. Mac Mail is constantly “Downloading Messages” often 30,000 or more, each time. Constantly taking up more of my 1TB flash drive. And exceeding my monthly 50GB of internet allocation. Actual mail size 35GB. Gmail Drafts size: 214GB. Final thoughts on how to fix Mac running slow. So we have run over the main methods to speed up a slow Mac. They all boil down to one simple idea: give your Mac some space to breathe. Eventually, any Mac is going to fill up with all kinds of garbage that's consuming resources, memory and disk space.

1. Too much history data and cache.

Safari stores information about every website you visit, and if you’re an average Internet user in 2021 it’s an awful lot of data. Plus, elements of those websites like images and html files are saved to cache so that pages load faster next time, which puts an additional burden on the browser. Imagine driving a car that’s packed with everything you ever owned: it’s bound to go slower than normal. So, try getting rid of the dead weight and see if Safari is still slow afterwards.

How to fix: Clear history and cache.

Normally, clearing history makes Safari empty cache as well, so try this method first:

  1. Open Safari.
  2. Hit History in the menu bar.
  3. Choose Clear History.
  4. Select the time span and hit the Clear History button.

This should do the trick, but if for some reasons you don’t want to lose your browsing history and just want to get rid of the cache, that can be done as well. Here’s how to clear Safari cache with more precision:

  1. Open Safari.
  2. Hit Safari in the menu bar.
  3. Choose Preferences.
  4. Select the Advanced tab.
  5. Check mark Show Develop menu in menu bar.
  6. Click on Develop in the menu bar.
  7. Select Empty caches

If you’d like to automate all of this, try a popular Mac speedup app, CleanMyMac X.
Os x 10.11 el capitan download iso download. Not only will it clean up Safari history and cache, but it will also clear app caches and other junk to lighten the load on your whole Mac. This is how you clean up cache with it:

  1. Launch CleanMyMac X (it has a free version you can download)
  2. In the app, hit Smart Scan.
  3. Go through the modules to review the files you’ll remove (cache will be in System Junk).
  4. Hit Clean.

That’s it, all the clutter including Safari cache is gone. And while we’re at it, let’s erase the browsing history, too.

  1. Go to the Privacy module in CleanMyMac.
  2. Select Safari from the list.
  3. Check the items you want to delete.
  4. Hit Remove.

Done. Try opening a few web pages to see whether Safari is still running slow. If the spinning beach ball in Safari didn’t go anywhere, check for other possible issues below.

2. Corrupted Preferences.

As you tweak the browser to your taste, like assign the homepage and search engine or pick where the downloads are saved, all the info about your preferred browser behavior is stored in a preferences file. When that file becomes corrupted, the browser can start acting funny. If Safari’s not loading certain websites, lags, or freezes, chances are the problem is broken Preferences.

How to fix: Delete the preferences file.

When you get rid of the corrupted file, the browser will simply generate a new one. Follow these steps to find and delete Safari’s preferences file:

  1. Close Safari.
  2. Open Finder and use the Command+Shift+G shortcut.
  3. Enter ~/Library/Preferences/ into the popup and hit Enter.
  4. Find the file named 'com.apple.Safari.plist' and delete it.

The only downside is that you’ll erase your browser settings and will have to recreate them. But if you use CleanMyMac X, you can make sure Safari preferences are broken before erasing them. That way, you won’t lose all your settings for nothing.

Fix broken preferences file with CleanMyMac X

Another way to check Safari’s preferences file and delete it if necessary, is to try the following:

  1. Open CleanMyMac.
  2. Go to System Junk and hit Scan.
  3. Hit Review Details when the scan is over.
  4. Select the Broken Preferences tab.

If the file is corrupted, it will be in this tab. Just hit Clean and delete it along with all the other junk. But if it’s not there, your Safari is probably slow for a different reason.

3. Buggy extensions.

Extensions let you do a ton of convenient extras in a browser, like store passwords or translate words with a click. But being third-party add-ons, they can impact Safari’s performance in unexpected ways, especially if they aren’t regularly updated.

How to fix: Remove the extension.

To find out which of your extensions is causing trouble, run a quick diagnostic:

  1. Click Safari in the menu bar.
  2. Select Preferences.
  3. Select the Extensions tab.
  4. Uncheck extensions one by one and see if the problem goes away.

When you’ve identified the culprit, hit the Uninstall button next to that extension in the Preferences.

As an alternative, go to CleanMyMac’s Extensions module and then Safari Extensions to remove any of them. Safari still running slow even though you’ve disabled every add-on? Let’s try the next thing on the checklist.

4. Autofill data.

Mac

Autofill comes in handy when you don’t want to memorize passwords and phone numbers, which is most of the time. However, when there’s a lot of autofill data stored, Safari might freeze for a few seconds before filling in every field. If it seems like the feature is annoying you more than it’s helping, you can just turn it off. Alternatively, you can disable only some of the options or remove the autofill data you won’t need.

How to fix: Delete autocomplete history.

To manage Autofill, do the following:

  1. Go to Safari and then Preferences from the menu bar.
  2. Select the Autofill tab.

Here you can disable any or all uses for Autofill (for example, never use it for credit card info). By clicking Edit, you’ll be able to look through the data that’s stored for autocompleting and delete the entries you don’t want there.

If you’d rather clean up all Autofill data in one go, it’s more convenient to do that with CleanMyMac X. You’ll need the Privacy module you’re already familiar with from when we cleared browsing history in Safari.

  1. Go to Privacy in CleanMyMac.
  2. Select Safari.
  3. Check Autofill Values.
  4. Click Remove.

If you still don’t have CleanMyMac, you can try it for free. The app will be helping you out long after you fix this Safari loading slow problem, because it’s packed with maintenance features that can boost the performance of your whole Mac, not just your browser.

5. Outdated plugins like Flash and Java.

In December of 2020 Adobe updated its infamous Flash Player for the very last time following its plans to discard the app altogether. But still, many websites require Flash and Java for Safari to play video or animated content. These plugins can drag the browser’s performance down if they are outdated, so the reason why Safari is running slow and gets stuck loading pages could be just that.

How to fix: Update Flash and Java.

It’s worth mentioning that big websites are dropping Flash and Java for a number of reasons (they are super buggy, for one), but if you absolutely have to open a website that uses one of those, check if your Flash plugin or Java need updating.

The best way to install the most recent Flash player is to download it from Adobe’s website. The page automatically identifies if the Flash player is up to date and will give you the download link if it’s not.

To check if you have the latest version of Java and update it if necessary, go straight to Oracle’s website. You’ll verify your Java version and get instructions on what to do next on that page.

That’s it, your browser should be back up to speed by now, so you can wave goodbye to Safari being slow. Just be sure to do regular cleanups and maintenance with CleanMyMac X, so that Safari keeps running like the wind.

Mac Downloading Slowly

Bonus: A few more things that may slow down your Safari

AdBlockers, similar to Adguard that work in real-time
Torrent-trackers
The macOS itself may need reinstallation
Your user profile got cluttered so create a new user profile
The final tip is to disable cross-site tracking and cookies in Safari. It's only available if you are running Safari 14 (2020) that came out with macOS Big Sur.
Click the Safari menu > Preferences > Privacy.
Check Prevent cross-site tracking.

That's all for now. Thanks for reading!

The following usually works on both Tiger and Leopard:
(First, if yours is an Intel Mac, check that Safari is not running in Rosetta, which is enough to slow it to a crawl.)
Adding DNS codes to your Network Settings, should gives good results in terms of speed-up:
Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu. Click on TCP/IP and in the box marked 'DNS Servers' enter the following two numbers:
208.67.222.222
208.67.220.220
(An explanation of why that is both safe and a good idea can be read here: http://www.labnol.org/internet/tools/opendsn-what-is-opendns-why-required-2/2587 / )
Whilst in System Preferences/Network you should also turn off 'IPv6' in your preference pane, as otherwise you may not get the full speed benefit (the DNS resolver will default to making SRV queries). If you want to know what IPv6 is:
This is Apple's guidance on iPv6:
http://docs.info.apple.com/article.html?path=Mac/10.5/en/8708.html
Click on Apply Now and close the window.
Restart Safari, and repair permissions.
If that didn't do it, then try this as well:
Empty Safari's cache (from the Safari menu), then close Safari.
Go to Home/Library/Safari and delete the following files:
form values
download.plist
Then go to Home/Library/Preferences and delete
com.apple.Safari.plist
Repair permissions (in Disk Utility).
Start up Safari again, and things should have improved.
