    New iMac supper slow , did I get screwed ??!!
    Hello ,

    In January , maybe March of 2018 , I purchased a new iMac , the 21.5 ,i5 , 3g , 8g ram with the 1TB. ( 5400 ) hard drive.

    This computer runs so slow its sickening ! , I have tried everything I could think of to get it to work correctly , My next step it to bring into Apple to see if there is something wrong with it .
    I have freed up as much of the HD as I could , I am only using 210.gb of the 1 TB hard drive .

    I have reviewed the above sticky ( How to keep your Mac up and Running for years ) however none of those suggestions have made any improvement , when I run Activity Monitor , nothing seems to be unusual to me ( However , I don't know what most of that stuff is , but it looks like most of it is system files and nothing is running really high.

    In my sheer ignorance , I presumed that the all the new iMac's had a SSD hard drive and that they didn't even make ( 5400 RPM hard drives ) so this was completely my own stupidity .

    with that being said , is there anything I can look for that could be making this thing so slow ? I have read that one solution is to boot the OS from and external SSD and this would give me better performance , however as some of you may have guessed that after spending $1400 on a computer that is only 6 mouths or so old , only to have to purchase a dedicated SSD is absoulty ridiculous , but trading it in for a 100 or so is even more ridiculous .

    I am a or I should I say I was a fanboy for a long time , my G4 867 MMD still works and my mid 2011 iMac works well also , actually this new one only works a little better during some task .

    And no , I do not use this for anything serious , as a matter of fact , I use this 90 percent of the the time to do Messages , e-mail and web browsing . I do write a little Python code , but very basic stuff , I just started a few mouths ago .

    Sorry for the rant , I really wanted to keep this civil but I get very angry just thinking about it and I am beyond the point of returning it to get a better one !

    any help would be greatly appreciated .

    Thank You
    John

    Welcome to the forum.

    When you say it's slow, can you be a bit more specific? Slow doing what? If all you do is Messages, email and web browsing, the main choke point is your internet provider. What speed lines do you have? How is the Mac connected? What have you tried already beyond cleaning up the drive and looking at Activity Monitor? You bought a new machine with a very slow hard drive, but once the programs are in memory, that doesn't matter.

    I can understand the frustration, but ranting about "it's slow" isn't much help to us to try to tell you what to do.

    MacinWin , thatís fair enough.
    When I first open iTunes , Photos , Pages or just about any other app . It takes what seems like for ever , Garage Band 30 sec. , Pages 15 sec. ( with beach ball )
    This is after a restart.

    I have have my photos all into one library on iCloud ( this was actually a bounus to me )
    I have free up my disk space .
    I have deleted most all 3rd party app. Most notably a Torrent app.

    I downloaded Onyx and that didnít seem to do anything for me .

    I am no longer connected via WiFi only from Ethernet ( the WiFi was way to slow on that machine) I have much better WiFi speed on my iPad , phone and older iMac ( and all these devices are with in reaching distance of each other ) I have tried shutting off WiFi on all of there devices and the WiFi is still slow on the new iMac .

    The Bluetooth keyboard and track pad intermittently have lag .

    When I launch an app , sometimes I have to click the icon a few times for it to open .

    I have not downloaded any strange app. I have also checked the root folder for any large files and Googled them to make sure they are part of the original OS files .

    All software is up to date ( have not installed Mojave yet , not sure if I should)

    It seems that the only solution is to install a SSD drive either internally ( not by me ) or externally .

    Hopefully I can get some other option to try on this forum if not maybe bringing it back to Apple my be the best solution at this time .

    Perhaps itís the machine that is faulty ?

    Exactly...got to know what you're looking at in order to come to the proper conclusions.

    It's possible you may have misinterpeted this suggestion. The suggestion of using an external storage device is not to operate things permanently like this...the external device is used as a temporary diagnostic tool.

    Also...you don't need to purchase an expensive external SSD...just get a cheap external spinner hard drive. Depending on your computers backup strategy...having an external drive can be a must anyway for backups.

    Maybe start off by posting some screenshots of what you're seeing in Activity Montitor.

    That is most likely the slow spinner hard drive showing it's lack of speed. About all you can do about that is to change to a faster drive.

    I have have my photos all into one library on iCloud ( this was actually a bounus to me )
    I have free up my disk space .
    I have deleted most all 3rd party app. Most notably a Torrent app.

    I downloaded Onyx and that didnít seem to do anything for me .
    Ok, those are good. Not sure about Onyx, it works for what it does, which is to clean up things that aren't needed and fix issues it finds. If it didn't do much, and if there was not much difference, then not much it can fix was wrong.

    I am no longer connected via WiFi only from Ethernet ( the WiFi was way to slow on that machine) I have much better WiFi speed on my iPad , phone and older iMac ( and all these devices are with in reaching distance of each other ) I have tried shutting off WiFi on all of there devices and the WiFi is still slow on the new iMac .
    Ethernet is definitely faster than WiFi, but even Ethernet into a slow internet connection from your ISP isn't going to solve speed issues. What ISP do you have and what speed is the line? Have you tried testing at Speedtest.net?

    The Bluetooth keyboard and track pad intermittently have lag .

    When I launch an app , sometimes I have to click the icon a few times for it to open .
    Neither of those is supposed to happen. Given you are still in Apple Care, I'd say take it back to Apple to have the genius bar test to see what may be happening with the lag and the mouse clicking on apps. Or try calling Apple support and work with them over the phone to see if there is a way they can save you the trip to the store. It's a PITA to carry an iMac around.

    I have not downloaded any strange app. I have also checked the root folder for any large files and Googled them to make sure they are part of the original OS files .

    All software is up to date ( have not installed Mojave yet , not sure if I should)
    Well, Mojave seems to me to be a bit quicker, but I don't think that's the issue for you. It's either the Internet speed or the slow drive, maybe both, and maybe something intermittent with BT.

    It seems that the only solution is to install a SSD drive either internally ( not by me ) or externally .

    Hopefully I can get some other option to try on this forum if not maybe bringing it back to Apple my be the best solution at this time .

    Perhaps itís the machine that is faulty ?
    Could be. The keyboard and trackpad should not lag, and launching an app shouldn't take multiple clicks. Those are definitely not normal. The speed is, as said, a combination of slow drive and maybe internet speeds.

    I'd say call Apple for phone support and if that doesn't work out, take it back to the store for testing.

    You might also get Etrecheck and run it and post the results here. You can find it in the Mac App Store. Free.

    any help would be greatly appreciated .

    Just for a test, you might want to shut down and then boot using Safe Boot Mode and see if most things work a bit better.

    Note: not all things work when in Safe Boot Mode.
    To get back to regular use, just restart as normal.

    Is Etrecheck free? The App Store says "In App Purchases" and the last time I checked his website, it was not free. Older versions which you can still find are free, although I don't know if an older version works with Mojave.

    I believe the current version gives one it's three free runs, then one needs to pay.

    I would doubt that it's going to show anything drastic as the OP has already done most of the maintenance stuff it's most likely to suggest doing.

    I'm also wondering if downloading and running the latest compatible Mac OS COMBO Update would help, but it wouldn't hurt.

    Doing a Safe Boot as I suggested previously should help clean up some surplus stuff that may help speed things up.

    Simple.

    You purchased an underperforming iMac with a slow as molasses 5400rpm laptop style drive instead of one with an SSD. You can attach an SSD via USB3 externally, clone over the contents of your hard drive, select the external in System Preferences > Startup Disk as the boot disk by highlighting (selecting) and you will notice a huge increase.

    Also alas to install more memory you have to crack it open and just about dismantle everything to get to the memory slots, not recommended by Apple. A 27" model has the door in the rear for user installation of up to four memory slots.
    Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    I would tend to agree and I'm just wondering if the OP purchased one of that era's models intended for lower school grades.

    But interestingly, even the lowest of such marvelous still have a decent Geekbench score that does not match the performance the OPD is getting.

    Geekbench 3 (32): 3869 Geekbench 3 (32): 15820
    Standard Storage: 1 TB HDD/Fusion* Std. Storage Speed: N/A
    Details: If configured from the iMac "Core i5" 3.0 21.5-Inch (4K, Mid-2017) (MNDY2LL/A), it has a 1 TB 5400 RPM hard drive by default. If configured from the iMac "Core i5" 3.4 21.5-Inch (4K, Mid-2017) (MNE02LL/A), it has a 1 TB "Fusion" Drive, which combines a 32 GB SSD and a 1 TB hard drive.
    https://everymac.com/systems/apple/i...017-specs.html

    But it sure does falter on whatever the second score represents for the basic model:
    Geekbench 3 (32): 3461 Geekbench 3 (32): 7674
    https://everymac.com/systems/apple/i...017-specs.html

    But I'm not even sure what exact model the OP has.

    Hello ,

    Thank you for all your feedback , I apologize for being a little dramatic and short yesterday . I appreciate the help you are all willing to give Me .

    The 5400 RPM drive can't be all that it is causing this machine to operate so slowly. If that were the case, Apple would never include a 5400 drive in any iMac. However, based on the Etrecheck report, your disk read/write speeds are what I'd expect to see from a spinning media. The 7200 version would probably do about 8-10 MB/s more (so not a HUGE difference).

    However, your Nominal I/O speed of 0.24 MB/s is concerning when other reports I've seen show close to 24+ MB/s. This would indeed causing a delay in launching anything.

    Was the machine slow from day one when you bought it?

    Agree with Ashwin...a slow spinner HD would not be the main cause of slowness. One test that I frequently recommend is boot the computer from an external storage device with ONLY a fresh copy of the macOS installed.

    When you do this...you can quickly determine if the computer is having a hardware or software/OS issue. This is a key step in how to approach further troubleshooting.

    macmechanic may well be the major problem.

    Download malwarebytes for mac and run in scan mode. Do not pay the registration fee as it will run the free version after the trial period.

    Using OS X.7 or later make a bootable USB thumb drive before running Installer!
