Safari very slow to load new pages

[pinkoos]

Hi,

My wife's Macbook Air (Sierra, all software updated) recently (within the last two days) developed a problem where Safari takes a very long time to load a new page. This is not specific to a particular website...any site takes very long to load, but it will finally load after maybe 30 seconds.

I've searched online and tried different things to fix the problem as suggested by people with similar problems: rebooting the Air, rebooting the router, turning wifi off/on, clearing Safari cache, deleting Safari prefs, changing IPV6 (in the Network Pref Pane) to "link-local," etc., but nothing has fixed the issue.

Chrome works just fine, so she's switched to using that for the time being, but I'd like to figure out what's going on with Safari and fix it.

My iMac (Sierra, all software updated), running on the same wireless network doesn't have this issue.

I've avoided changing the DNS (as suggested via my searches) b/c my iMac doesn't have the issue.

Any thoughts or suggestions?

Thanks.

Have you tried a new user account, or restarted in Safe Mode and restarted again? Have you checked for malware?

pinkoos,

Filliam is on the right track. Follow those suggestions. Something has happened about two days ago to cause this. Run DetectX and MalwareBytes to see what may have been installed.

pinkoos,

You could also try booting from a backup clone of her Mac that is a week old (if you have one) to see if the problem is there too. It would be nice to prove how recent the change occurred.

Thanks for the replies. As I'm at work, I will have to try and troubleshoot more with your suggestions this evening.

.000000000000000000000000000000000000% chance its malware.

Which seems to be the answer to everything "my mac is slow" on this board these days. :RollingEyesSmiley5:

Have you checked Flash, I know there was an update not long ago.
