Excel for Mac Running Very slow

This worked like a charm! Thank you!

When I got to this part of cleaning up the fonts, there is nothing in the FONTS (REMOVED) folder and now this seems to have affected my Word doc formatting and translating to pdf formatting. Any advice???

I'm running on Macbook pro OS X 10.9.1 and with the new mavericks update :/

7) Open your OS Library and look for the FONT folder. You should also see FONTS (REMOVED) and FONTS DISABLED. Open the FONTS (REMOVED) folder and find the MICROSOFT folder. Drag this back into your FONTS folder…it will proceed to copy over. i.e. a copy will remain in FONTS (REMOVED) and a new copy will be formed in FONTS.

Jculverfit,

Sorry, but I don't have any suggestions.

I wrote that process one year ago based on my research and what was happening with my machine running 10.8 (as I stated in my original post). Since that time there have been several updates for MS Office and of course now OS X is up to 10.9. There is a high likelihood that those steps are no longer applicable with MS Office and 10.9...unfortunately that is how things go with technology upgrades.

Hopefully someone else can weigh in and offer you some further advice.

Well I finally upgraded to OSX Mavericks yesterday after our company finally gave the green light and so far I have to say I am happier with the performance of Excel and Word when opening and closing as well as editing. Maybe there were some improvement behind the scenes. Anyway if it gets back to its usual slowness I will certainly post back here.

Me too, also I have a new MacBook Pro rocket which is incredible 😉

Man, this works! Don't bother trying everything else!

Thanks, mate!

UPDATE to a post which I made earlier which apears to have been quite successful.

I have also found a problem with ADOBE fonts included in Acrobat Reader. There are a couple of fonts ArialMT and TimesRoman which appear to also conflict with MS Office.

If you have these two fonts anywhere sometimes MS Office looks for them and starts to use them, and this also seems to impact performance.

These fonts are sort- of needed by Acrobat Reader, but if you use the built in Apple program "Preview" then Acrobat Reader is probably not needed.

If you want to test this, just copy the fonts to a USB stick (as a back-up) and then delete them from the Adobe Fonts folder.

It worked for me on Word! It has been like that for about a year now. If only I had googled it earlier.

Thank you so much Chris for the tip on the fonts for a slow running excel! I have been dealing with this for a LONG time! Thank you thank you!

I followed all of the instructions detailed above in order to fix the font issue. However, I got stuck on #7. I can't find a folder anywhere that is labled Microsoft. Help please!

Hi, I'd like to share my experience which is a bit different from other shared on this thread.

I switched from Windows XP to Lion on my PC.

The Mac Office was unable to open my Excel accounting spreadsheet correctly because of problem with date formats.

So apart from being ridiculously slow MS on Mac could not leave the sheet in Win compatible form.

What I did was to create a VHD image of my Win system and loaded it on Lion via VirtualBox in Seamless mode.

Now apart from Dock on a rigth side of screen I have Windows Start strip on a bottom.

The Excel still was twice as slow.

I upgraded my CPU to 4 core one from 2 cores to have 2 dedicated cores for VirtualBox. Still too slow.

Then I stumbled on this thread and switched to Manual in Excel Options \ Formulas \ Workbook Calculation and disabled Enable background error cheking on same tab.

Now my complex lookup formulas respond instantly.

Hi Guys!

I tried all solutions with fonts but unfortunately nothing work 😟 My excel is very slow, I can't use it. Have you found any other solutions? I will be very grateful for help. I have Macbook Pro with Retina, 2.4 Ghz, i5, 8 GB.

Best,

Bartek

i started having lagging problems with Excel ever since i updated to Mavericks.

cell copy-paste took 3-5 seconds every time even within same sheet, work was impossible.

it worked well under newely created user though.

i tried everythig - fonts validation, restoring, deleting, deleting Excel preferences, reinstalling Office - nothing helped.

eventually i made a startup USB disc, erased everything and clean-installed Mavericks - problem is gone, everything is super fast now. hope it helps

Had the same problem, and this worked like a charm. I owe you one!

This solved my problem big time! Thanks much!

A couple of weeks ago Excel started acting really weird: long delay to open a file, frequent crashes, long time to save a file, etc. While the ball was spinning as I was waiting for Excel to complete some action, I looked at the Activity Monitor and noticed that Excel was using 100% of my CPU. As soon as it completed the task of opening or whatever, then the CPU % dropped back to normal.

Per your suggestion I went to MacintoshHD:Library:Fonts

All of the fonts in this file had a date that was at least 6 months old except for the following list which displayed a recent date modified.

I dragged them out of Fonts, put in on my desktop, restarted Excel and had no more problems.
