Browsers & Downloads suddenly grind to a halt!

I'm an infrequent user of the forums. I appreciate any guidance.

I have a Macbook Pro 11,2 running Sierra OSX 10.12.6. SSD hard drive installed by OWC with 16GB RAM. I purchased the machine used from OWC in February and have had NO issues. All has ben performing beautifully. However, late last week everything has ground to a halt. Browsers (Firefox and Safari) take 30sec to 1 minute or more to load a simple webpage. Download of 49MB took more than 10 mins. Home network appears fine as other Macs and devices in the house have no such issues. Took me 20 minutes to download Etrecheck from the App Store. Most other functions on the computer seem to be ok, or at least nothing as noticeable.

I ran Malwarebytes and came up clean.

Here's the Etrecheck report:

End of report

I pulled my Time Machine backup drive off the computer as soon as I realized that there was a serious problem, not wanting to possibly corrupt a back up in case I'd been the victim of something malicious. My website visits are pretty harmless (I think). News, etc. Amazon. I'm fearful of something running in the background collecting data, but I certainly don't know how it might have gotten on my machine. I don't even use other wireless networks (except inside corporate client environments). I was on one last week when I noticed things start to slow down.

Truly sorry for the long explanation, but I don't know what to do. I'm not using any cloud backups or anything that might cause an obvious slow down. But, the time it takes to load the simplest of webpages tells me something is seriously wrong.

Thanks for any help you can offer!!

Have you tried running a speed test? (from google, search for "Speed Test")

You have a lot of 3rd-party kernel extensions and background programs. You should try running in Safe Mode and see if that makes a difference. If it does, one or more of these are likely causing the problem. The report says you're running Sierra and it may be that if you've upgraded or added any of these recently, they might not work well with Sierra.

I also noticed you have startup items for MobileMe, which Apple put to rest some time ago. You may benefit from going over the various startup items listed and removing those that you don't use.

Looks like you restored the system from an old Time Machine backup. You have some pretty old WD drivers in there. Update them, or uninstall if you don’t use the drive(a) anymore (I suspect it’s probably what you use as your Time Machine drive, but I could be wrong.)

If you have an external drive attached, and it’s having an issues, it can slow your whole system down when it tries to access it for reading or writing data.

Also, you installed Adobe Flash Player on 11-JUN-2019. About a week ago, shortly before you started experiencing these issues. I’d uninstall that too.

While you’re doing that, go over all the other stuff you have installed and verify if you still need it. If you still need it, update it to a release that supports macOS 10.12 (lots of stuff from 2008-2013 on there.) if you don’t need it, or can’t get an update to support 10.12, then uninstall it.

Thank you ALL! I'm grateful for your expertise. Here's what I've done since reading your responses:

1) Speed Test - I performed this first on my wife's iMac running Sierra because we're both wireless on our same Comcast internet. Her speed was 32.76 Mbps Download 5.91Mbps Upload. Mine on the same network was 0.46 Mbps Download and 0.60Mbps Upload. YIKES!!

2) Uninstalled Flash Player. I've heard unreliable things about Flash Player, but had to install it last week to purchase baseball tickets from MLB Team's website. It is now uninstalled.

3) Booted in Safe Mode (Thanks! Never done that). All booted fine, but same browser hang ups. Ran a Speed Test and results were 1.04 Mbps Download and 1.07 Mbps Upload.

4) Rebooted in Normal Mode - All booted normally. Ran a Speed Test and results were 0.18 Mbps Download and 1.45 Mbps Upload. UGH!

5) I primarily use Firefox and when this started happening a new version was available. So, I upgraded to 67.0.2 hoping it would fix the issue. It has not. I'm having the same slowness issues with Safari 12.0.3.

6) You are correct that My Time Machine backs up to an external WD hard drive. It has been disconnected throughout this process as I didn't want anything harmful to find its way to the back up. There have been no external drives connected since last week.

7) I purchased this MacBook Pro used from OWC. It was fresh with a new copy of Sierra and I set it up as mine from a Time Machine backup from my old 2011 MacBook Pro, which was transferred over from my old 2008 MacBook Pro. That's probably why there's some old stuff in there (like anything related to Mobile Me).

So, The Flash Player is the only thing that I can think of that's been newly introduced around the time things started slowing down. It's now gone and I'm still having the same issues. I'd be happy to delete anything that's unnecessary, but am unsure how to do that (especially with anything like a "kernel extension"). I apologize for my lack of knowledge.

Any links or guidance are greatly appreciated. Again, thanks so much for your time!

Thanks, they both look ok. Well, you know, crap, but ok, all things considered. :). Certainly I wouldn't expect to see the sort of degradation you're seeing.

You could spend a bunch of time trouble shooting this, wifi problems can be tricky, but I would consider two courses of action:

1- Buy a replacement router. Preferably one that support 5GHz. Configure your 5GHz and 2.4GHz networks separately, and try it just on a 5GHz connection.

2- Backup, wipe, and from a non-restored clean OS, see if the Macbook still shows the same issues.

I'd probably start with option 2, though option 1 might be more fun.

If you want to troubleshoot, in no particular order you could:
* ensure that all USB devices (including USB hubs) are disconnected for all awake computers that are nearby,
* reboot the router and MacBook Pro, backup router, hard reset router, and reconfigure your router (don't restore),
* create a guest account, reboot, login as guest without logging into your primary account, and see if it's still poor.
* take your Macbook Pro to another network (maybe there is a coffee shop nearby) and see how it runs with speedtest.

Aside from Flash Player, you have a lot of obsolete software running on that machine--53 32-bit apps!

Notable plug-ins that are obsolete:

Additionally, many of the other plug-ins are just plain old. Look at their install dates. 2008?

You might benefit from backing up all of your data and doing a clean install. Then on a case by case basis, install the applications that you really use and that are up to date.

Thank you all for the suggestions!

Just a few more questions from a less knowledgeable person... :)

How are you assessing what software is old? In my Applications? I don't know how 53 are obsolete when there are only 59 Applications in my Applications folder? You're referring to background applications of some sort? How do I asses what I can delete of my plug-ins? I deleted Flip4Mac and Silverlight (I think). I'm sure there are old things that just got transferred from the Time Machine backups of the older MBP's and I'd be happy to delete them, I'm fearful of deleting something that might be important to operation. Sorry to be a bit dim on this particular issue.

I know how to do a clean install, but the OS was preloaded when I bought the machine. So, I don't have a copy. Is there somewhere that I may download a legit version of OSX Sierra? The last time I asked Apple Support for a copy of an older OS, they got pretty terse and uncooperative.

The browsers are still running slow. I'm eager to try your suggestions. Thanks again for your guidance. You've all been really helpful!

Buy a new router is probably the best way. You're connected on N which is quite old at this stage. Could be any number of thins with the router, the connection protocol, the channel congestion, MTU etc. Honestly, just try use a newer decent router. There shouldn't be anything wrong with the actual laptop and I fear you'll spend days trying to solve this one.

Connect your MacBook Pro to your wife’s iMac with a USB-C-to-A cable, and start the iMac in target disk mode. Then, power on your MacBook Pro and hold down the option key. You should see the iMac’s drive as a boot selection. Boot from it, and test the WiFi.

When you’re done, shut down the MacBook Pro first, and then power off the iMac by pressing the power button until it turns off.

You can read more about Target Disk Mode here, as I haven’t covered it all:
