Safari is slow after Mojave update

Same here. Safari 12 on Mojave is virtually unusable for me, loads pages very slowly, regularly just stalls and generally has a detrimental effect on the whole system. A good example is YouTube which stutters and runs terribly. Moved across to Chrome and all is well so until this is addressed by Apple I'll be using that.

My Macbook 13" 2015 has the same problem. Sometimes the Safari stay everything black and stopped the computer.

I don't have any problems with others Browsers, I was waiting for an Update and until today has nothing.

I have to use chrome for some things like Google forms, and now I've been using it much more. It works with adblock plus well, but now safari doesn't at all.

I'm not a fan of chrome generally, but now the update doesn't work in full screen--quite annoying!

If you have Ad Blocker enabled in Safari, try turning that off. Recently Apple deprecated an API that is frequently used by Ad Blockers and it looks like the new replacement API is not as fast as the old one (no proof, just a speculation).

I've also had a serious issue with safari after updating to Mojave. I've noticed the problem for safari on my MBP is mostly surrounding google owned companies such as youtube, gmail, google search engine, google drive, etc. I use all of these on a daily basis so it would be really helpful if Apple stepped in and figured this problem out. I love to use safari but this issue has really turned the tables.

I have the same problem. Overall the speed of Mac has slowed down, and especially in Safari, PDF files are not formatting correctly on Zooming in. They split in two half in a non-readable and unacceptable fashion. The words get distorted etc.

I actually spoke to someone at Apple the other day. They said they believe it is because Mojave is more frequently connecting to icloud--too much, so even typing in notes is delayed.

Hopefully a fix will be rolled out soon but it seems to be a very common issue. I have one of the top-of-the-line MBPs so I know it's not outdated hardware.

Since I installed Mojave, iTunes is screwed up too. It only recognizes my iPhone 8Plus and not my Mac Pro laptop, iPod nano, shuffle, touch, or iPod classic whereas everything showed up in devices before. Also I had 19,300 songs in my iTunes library of which 9,320 show up now and only 113 are downloadable because they were purchased in Apple Tunes, my others that I transferred from CD or vinyl are gone! They aren’t even in the cloud! Some of those were rare vinyl from the 30’s thru the 70’s and a lot were ethnic music since I do an ethnic radio program on the web and over the air for the local Balkan community and now they are gone! Apple is getting to be like WINDOWS and MICOSOFT! Let’s release it before all the bugs are out. I contacted Apple tech Support and they had no answer how to solve either issue.

Same problem on iMac (Retina 5K, 27-inch, 2017), 3,5 GHz Intel Core i5, 24 GB 2400 MHz DDR4 - with no 3rd party plugins installed on Safari.

The loading of websites in Safari is very slow & laggy 😐

I called in to the Stormfront shop in Carlisle yesterday and asked the question regarding macs and MacBooks being slow after the recent OS update and was told that the file system is optimised for solid-state hard drives and a clean install of the OS could solve things. I was also told that my 2012 MacBook pro would be good for another 3-5 years if upgraded with a solid-state hard drive. I'll have to see how many pennies I have to spare after Christmas!

Me too, ABP was the problem of the lagging Safari. I tried several others like Adguard but settled in with 1Blocker (v 1.4.3) which works wonderful and integrates with Safari content blocker api. (This is a benefit since older adblockers are able to see all the content on the sites you visit.)

I have the same problem too on both my iMac(27 inch,late 2013) and MacBook Pro(13 inch,2018,touchbar). I've tried all suggested solutions on both of my devices.. nothing. Since I've updated to Mojave, Safari is extremely slow.I even upgrated my iMac's RAM(+16GB).Everything is slow and not responsive like it should be .Even when I write something on some websites like messenger for example I see the letters some seconds after I press the keys. I tried other internet browsers both Firefox and chrome and both are working fine, so I'm 100% that is safari's problem on this version of Mac OS

Sorry to tell you, but Safari was slow befor Mojave. Die hard apple guy here. Just for the heck of it I decided to try the newest Firefox. Downloaded and installed Firefox, adjusted a few of the settings and ran with it for a while. Amazing the difference. Firefox blows the socks off Safari. No delay in loading web pages, no more annoying web site full page advertisments. Firefox is so noticeable faster than Safari that I began useing it as my main browser.

Hi, I have had the problem with Safari stalling when going to Google sites, Docs, Drive etc - I fixed this by ditching all of my Ad Blockers , clearing history and removes cookies (in Privacy in control panel). It seems to be going better now. Cheers Graeme P

Having used Mojave for about three months now, I feel I can provide a good update as to what are the issues at hand and what can be solved:

-Everything is slow: disable ad-blocker, and any other extensions (like Honey, which made Amazon unusable)

-Specific websites are slow: try disabling extensions, but sometimes doesn't help. (Thesaurus.com is nearly unusable)

-The notes app is delayed when typing by one second, two seconds, three seconds......unfortunately a major flaw, supposedly (from what an Apple Genius associate told me) caused by significantly more frequent iCloud updating (like on a per-character basis, versus waiting a few seconds)

Final remarks:

-Mojave is beautiful, advanced, intricate

-Mojave is well polished, at the very least design-wise, if not glitch-wise

-Mojave is NOT OPTIMIZED for certain executions (like extensions, notes, websites) which is a major flaw and a massive deterrent to use of the otherwise highly applaudable operating system.
