I've been asked to help with a iMac showing the beachball and being very slow.
The problems started after installing security update 2019-002 and Safari 12.1.
The OS was Sierra (10.12) first, then updated to Mojave (10.14) which did not solve the problem.

I have a screenshot of Activity Monitor:
There I see Safari is using 30.31 GB of memory and 29.64 GB compressed memory, 8 threads, 358 ports.
Memory pressure is red, general information about memory is
8 GB physical
7.54 GB used
  953.4 MB app
  1.10 GB wired
  5.50 GB compressed
459.3 MB cached files
662.0 MB swap

All accounts on that machine are affected.

I assume that heavy swapping is going on, slowing down the iMac. (I don't know whether it has a SSD or a HDD.)
However, what I don't understand and what puzzles me, is how Safari can use 30 GB of memory when there is only 8GB physical and only 662 MB swap space (that being "The space used on your startup drive by macOS memory management.").

That's my main question. But of course, any help on how to go about solving the problem is very much appreciated, too.
I need a GUI client for sftp on MAC.
I have downloaded cyber duck. And i could connect to a sftp machine with port 22.
But then i tried another machine with port 7122. It seems it doesnt have ability to handle this port.
Although i am able to connect if from terminal.
On cyber duck if i manually change the port to 7122 it doesnt work.
It throws the following error :
Please help in suggesting some way to connect to this through some GUI client.
Mac isn't showing other users so another user can't login to the Mac.

The mac was binded to Windows Active Directory to allow users to login with their domain account. We have found that sometimes the option to login with another account just disappears and does not reappear even with a restart to the Mac. The temporary work around I've found is that if I login with the local admin account and just go through the same steps of binding the Mac (Even though it has been binded already) and then just log out the Other User option appears on the login screen.

So my question is there a more permanent fix so this doesn't keep happening?

MacOS 10.14 Mojave
Using Quickbooks for Mac 2016.  When I open one of my company files, the Customer Center window opens, because I had it open when I last closed Quickbooks.  Then I see 3 or 4 other windows open and disappear (a Deposit window, a Timesheet window, I think.)  

When the window-opening animations complete, the one open windows can be dragged into new positions, but not resized, and not closed, and does not recognize any mouse or keyboard interactions.  The program itself displays every menu item as hidden.  I have to Force Quit Quickbooks to take it down.

I tried reinstalling the program, but I get the same behavior.  Odd, because this company file was working fine just two days ago.  I back up every time I close the file, and I've tried restoring some recent backups, but they behave the same, even backups taken from a week ago.    Not sure what to do next.

Time Machine couldn't complete backup to "[Name] Time Machine"

With 2 Macs (Mojave), I am unable to continue Time Machine backups. I have to erase drive to continue.

Seems in the past with earlier OSX versions I could rely on Time Machine to delete older files and continue with backup.

Why not now? Can I automate the erase/restart backup procedures?
Hi guys

My father's 27inch early 2011 imac needed a little upgrade. I went and put in a Crucial 500gb SSD disk into it into where its old hard drive used to be.

When we boot, i am getting the question mark with a folder. I tried holding the Alt option and in doing so only the internet recovery comes up. I tried command R and same thing.

Anyway, so I chose the internet recovery. It took 20mins. Then it came to the menu where I could choose disk utility. I went in and could see the SSD.  I formatted my SSD to Mac format (journaled). I restarted it and still same. Then i tried doing something similar to choose it as the startup disk but I can't. I tried attaching an external disk with Mac Sierra installation on it. It isn't giving me the option of seeing this disk either at startup.

What gives? Is it the Mac itself? Should I take the SSD and install it onto a MacBook Pro and try putting the OS on it that way?

Thanks for helping
HI there,

i'm trying to get an iMac running OS X 10.8 (Mountain Lion) to boot up again. It was constantly freezing up with the a continous spinning wheel so i was recommended to "Repair Disk Permissions", after doing this it will not boot back up again. It boots into recovery mode, asks me which language i want to use then i get
OS X Utillities -
Restore from Time Machine Backup
Reinstall OS X
Get help online
Disk Utility
There is no Time Machine backup so i opened Disk Utility and ran the various verify/repair disk & have included screenshots of the results.
I also ran diskutil list from Terminal & included the screenshot aswell.
I guess first think i'd like to know is if it's possible to back up my files from here & secondly is it possible to get it to boot up again without reinstalling. Also is this a sign that the hard drive needs repalcing?
I'm a novice with Macs & OS X so be as detailed as possible please & as always all help is much appreciated.

I have an issue with disappearing shortcuts of shared folders between two mac machines. Here is the case in details:

On MAC1 there are 10 folders on the desktop that are shared on the network. They are accessible and visible on MAC2.

When I created shortcuts on the desktop of MAC2, they work fine until MAC1 is rebooted. Then a warning message appears and shortly after that the shortcuts are gone.

Is there a way to resolve this issue?

MAC1 is running macOS Yosemite 10.10.5

MAC2 is running macOS Mojave version 10.14.3

Thank you

We are a school and I have created a single School iCloud account. I have added all the 4 iPads into the school iCloud account.
Using the school iCloud account, I have installed the default apps and updates on all the 4 iPads.

I will be issuing these iPads to the staffs and will they be able to use their own personal iCloud account and install their own apps on the school iPad?

We are a windows-based network and the iPads are only for the senior management and we will not go more than 8 iPads.

Any help and sugessions will be great
Thanks in advance.
Hi - I am about to replace the HDD of a client Macbook mid 2012 with an SSD drive after the former had failed.
Is there a way that i can install High Sierra or Sierra on the new drive straight from an external USB disk instead of going through the Internet recovery?
Otherwise it means it will install Mountain Lion and then i have to re-upgrade again which is a waste of time i would like to avoid if poss.

MAC computer (macOS 10.14 Mojave) is able to successfully connect to corporate network via Anyconnect mobile vpn client. But when attempting to map a shared network drive to a windows server share it hangs and finally times out after 2 minutes or so and wont map the drive. Yet there are 6 other MAC's with macOS 10.14 Mojave that do not have this problem.

Tried pinging the windows server from the MAC after successfully connected to the VPN and it will continuously times out but there is a reply to ping every 15th ping request for about 2 pings and then go back to not responding to ping for another 15 pings.

When pinging MAC from the windows server it will ping successfully continuously!

I already plan on performing apple diagnostic on the MAC next but I am not too familiar with Macs and want to see if there are any other suggestions from the community!

Appreciate any other ideas....

 I have Outlook 2011 on Mac, installed Outlook 2016, and created a new email account and working fine.
 The task is to export the email, contact and calendar items from Outlook 2011 and import them into Outlook 2016.
 I created OLN file (about 6GB in size) from Outlook 2011 and imported into Outlook 2016, but there is no data when import was finished in a few seconds.
 What other import/export option is available?

Thanks in advance.
I have an ASUS 3200 Router and heard that I could use it and its USB connection to make a backup location with a hard drive connected to it. I have only one USB port but two laptops I work from. One a Dell Vostro and the other a MacBook Pro. I am wondering since formatting the HD is an issue here. Can I create a partition and format one side for a Windows backup and the other for a Mac? I know it involves formatting the disk which I do know know if one can allow the other to save to or not and the location of the HD's drives. File Path.
Does anyone know if this can be done in any capacity? I also have a USB splitter that could double up the ports but do not know if that would work either with two separate HD's with two connections? Any Help Appreciated.

I have an Excel macro that uses ActiveX but it doesn't work on my Mac since ActiveX is not supported (get a 429 error). It does work on my PC but I've transitioned over to a MacBook Pro.

Can the following code be converted so that the Excel macro work on my Mac?

Sub GetEmailList()
Dim lr As Long
Dim x, y
Dim dict1 As Object, dict2 As Object
lr = Cells(Rows.Count, 1).End(xlUp).Row
x = Range("A2:A" & lr).Value
lr = Cells(Rows.Count, 2).End(xlUp).Row
y = Range("B2:B" & lr).Value

Set dict1 = CreateObject("Scripting.Dictionary")
Set dict2 = CreateObject("Scripting.Dictionary")

lr = Cells(Rows.Count, 3).End(xlUp).Row
If lr > 1 Then Range("C2:C" & lr).Clear
With dict1
   For i = 1 To UBound(y, 1)
      .Item(y(i, 1)) = ""
   Next i
End With

With dict1
   For i = 1 To UBound(x, 1)
      If Not .exists(x(i, 1)) Then
         dict2.Item(x(i, 1)) = ""
      End If
   Next i
End With
Range("C2").Resize(dict2.Count).Value = Application.Transpose(dict2.keys)

End Sub

Open in new window

Any ideas experts?
I am using Outlook on a Mac OSX and my email mailbox size has grown to 47GB.  I have increased my mailbox online to accommodate a mailbox larger than 50GB+, but I was curious if I was going to run into mailbox size restrictions in Outlook similar to a Windows machine.  If so, is there a way to increase this max mailbox size?
