I have a 21" Mid. 2011 IMac running 10.13.6. 16 Gigs of ram. I updated to 10.13 several months ago. Two issues have developed in the last few weeks. One is when you start up it boots as it should. When you wake it from sleep it takes about 10 seconds to display the password box. It used to come up right after you touch the trackpad. I can live with this. The second issue is IPhoto does not scroll smoothly. It does a lot of jumping up and down in pictures, albums, and events. I migrated the IPhoto to Photos and I don't much care for Photos. I reistalled High Sierra, updated, and replaced IPhoto in applications and Applications Support and it done do good. Is there any thing I can do to repair the second issue other than a format and a new operating system that there is no guarantee it won't do it again. I have a 4 Terabite Hard drive with about 1 1/2 Terabite taken with pictures and video which takes a considerable amount of time to replace on a new operating system. I really would appreciate some help. Thanks. Jeff.
 
I'm curious as to how exactly a slow hard drive might cause user interface jitter in Photos o_O

Neither Photos nor iPhoto load the full-size photos in real-time off the hard drive / SSD while you're scrolling. There are tiny preview images saved in your photo library that it defaults to, and it should be buttery smooth when scrolling the same way iPhoto is. The fact that it is not might be an indicator of poor programming on Apple's part but I don't have a Mac that old to verify - on my 2017 with 1TB FD scrolling through Photos is as smooth as can be.
 
If your hard drive is a spinner the answer is there. Consider installing an SSD with operating system on it as boot drive, and use the current 4TB drive as an external via Thunderbolt if possible for your photos etc.
The 4 T hard drive has been in the IMac for 4 years. Why now after 4 years a issue? Thanks. Jeff.
 
Don't worry about it, your hard drive is not the issue here. It's sort of Pavlovian conditioning around here that whenever a Mac is slow people always point to the hard drive first without taking anything else into consideration.

On photos the scrolling is as smooth as it can be. The issues is in
iPhoto. Thanks. Jeff.
 
Oh, okay. My bad then, I misread that.

In that case it does not surprise me. iPhoto has been discontinued by Apple a long long time ago, and it has not been updated for YEARS. It's very possible that this jittery behavior is a simple incompatibility between iPhoto, High Sierra, and your GPU driver. iPhoto on High Sierra is unsupported, and it's quite possible that there won't ever be a solution to your problem. In fact, if I remember correctly it has not even been supported in Sierra anymore.

The successor to iPhoto is Photos, and it does pretty much everything that iPhoto did. To be honest I don't really see what iPhoto would do better than Photos, care to elaborate?

I guess I like IPhoto better because I have been using it for long time. High Sierra has been on the IMac for about a year with no issues. Why the non compatibly after all this time. I have a 2012 MacBook Pro with Mojave on it and IPhoto works great on it. Apple seem to have a practice to not let new operating systems interfere with older application although ITunes 12.6 would not work on my new IPhone 8+. I had to update to 12.7. I avoided that till the last minute so I would not have to deal with the app stuff one at a time. I guess I will have to go to Photos. Thanks. Jeff.

That's the thing with unsupported software: it may work, but it can also break any time due to seemingly random and completely unrelated reasons, for example because of a security update.
 
Move from iPhoto to Photos. That should solve the problem.

Replace the HDD with an SSD and it wil feel like a new iMac (except that Mojave is useless on these). Put that 4T drive in an external dock and use that to store your photos. USB 2 is fine for this.
