Mavericks makes Flash Slow on safari, Mavericks makes Flash Slow on safari

Safari Slow after Mavericks install.

My Fix.

In order below try:

1) System Preferences -> Flash —> Advanced -> “Browser Data and Settings” -> “Delete All”

2) Safari -> “Reset Safari” (make sure you clear everything).

3) Reboot your machine.

Try the misbehaving website…all should be well.

If not:

4) Safari -> “Reset Safari” (make sure you clear everything).

5) Exit Safari

6) In Finder go to ~/Library/Caches

remove com.apple.Safari

7) In Finder go to /Library/Caches

there may be a file or directory with “Safari” in name…remove it.

8) In Finder go to ~/Library/Preferences

there may be a file com.apple.Safari.plist , remove it.

there may be a file com.apple.Safari.Extensions.plist , remove it.

9) In Finder go to ~Library/Saved Application State

there may be a file com.apple.Safari.savedState , remove it.

10) Reboot your machine.

Try the misbehaving website and all should be well.

If not:

11) Safari -> “Reset Safari” (make sure you clear everything).

12) In Finder go to ~/Library/Caches

remove the file com.apple.nsservicescache.plist

13) Reboot your machine.

Try the misbehaving website and all should be well.

If not:

14) System Preferences -> Network -> Advanced -> DNS

The IP Addresses here should be “greyed out” numbers.

If they stand out as “black”, you may have a conflict with your ISPs DNS Servers.

If they are in “black”,

a) Note the numbers down on paper.

b) Remove them

c) Apply

d) Check that the numbers are now “grey”.

15) Reboot your machine.

Try the misbehaving website and all should be well.

If it is anything else…you are on your own…

LIke the other threads about this topic, what makes Mavericks run slow is the left over caches from the previous version.

eg: just google "Mavericks runs slow".

These caches merely hold your "preferences" and "previous settings" and the like.

They get recreated the software program starts again.

I have seens a number of upgrades, including my own, exhibit this issue of slowness.

I have managed to get a formula down as described above.

In this case Safari Flash Plugin, Safari itself, and DNS Server, any one, or perhaps all can be an issue.

(So I ask youto stop if your issue goes away).

You can monitor what is hapenning on your machine by:

1) Enabling "Developer" on Safari, and then opening a "Web Inspector window"

2) Openning "Activity Monitor", watching the Network Packets, and CPU.

3) If you have a Network Monitor like Little Snitch, it discloses more info about comms to

other hosts, via mDNSResponder.

A rather more heavy handed approach to a slow running Mavericks in general, would be to remove all caches

in all locations, local to the users and System wide...but then then reconfiguring all software is just tedious.

As some have suggested, the best method to avoid all this is to

a) backup

b) install 'as if' onto a new disk

c) restore

anyway.....let me know how you go.

ps - an an addendum…I have done some 8 upgrades using method above.

Then the 9th went sour. No improvement for Safari speed.

In the end I had to:

16) Safari -> “Reset Safari” (make sure you clear everything).

17) Exit Safari

18) In Finder go to /Library/Caches

there may be a file or directory with “Safari” in name…remove it.

19) In Finder go to ~/Library/Preferences

there may be a file com.apple.Safari.plist , remove it.

20) De-install Flash Player using the Adobe uninstaller.

21) Reboot Mac. (at 1st I tried it without a reboot, but it did NOT fix Safari speed).

22) Install Flash Player from Adobe.

23) Reboot Machine. (This was just paranoia.)

All was now well.
