'cursoruiviewservice' Not Responding and Causing Lag on MacBook Air

Hello everyone,

I've noticed that the "cursoruiviewservice" process in Activity Monitor is becoming 'not responding' and causing significant lag on my MacBook Air, especially when typing and switching between upper and lower case letters. It appears this process also controls the blue caps lock indicator, which stops working when the process is unresponsive. This issue seems to cause the lag, and currently, it is using about 170MB of RAM.

I'm avoiding restarting my MacBook as I've raised this issue with Apple Support and may need to provide logs again. Additionally, the "com.apple.hiservices-xpcservice" process also becomes unresponsive, though it usually doesn't exceed 3.5MB of RAM.

This seems to be related to an XPC (Cross-Process Communication) error. Some logs also suggest that Microsoft Outlook is not handling the clipboard process correctly.

Has anyone else experienced this issue or found a solution?

Thanks

MacBook Air 13″

Workaround (may need to run with `sudo` to persist): 

`defaults write /Library/Preferences/FeatureFlags/Domain/UIKit.plist redesigned_text_cursor -dict-add Enabled -NO`

📣 Guys, as I told you before, I have reported this issue to Apple multiple times, sent them logs, and posted about it in the forums. I even showed them the responses from these forums. Thank you to everyone here who shared that they were experiencing the same issue. Finally, Apple engineers investigated the issue and discovered that it's a software problem affecting M-series processors. They’ve informed me that they will be fixing this issue in upcoming updates. 👏🏻

Again!

I did a clean install
I didn’t install any third-party applications.
I didn’t even sign in with my Apple ID
I didn’t change any settings!

Yet, the "com.apple.hiservices-xpcservice" process continues to be unresponsive. "CursorUIViewService" hasn’t become unresponsive yet, but the RAM usage keeps increasing. I assume this will also become unresponsive eventually.

Please, if you don’t have a suggestion to contribute on this matter, don’t confuse the users experiencing the same issue here.

Here are the main possible reasons why the com.apple.hiservices-xpcservice process becomes unresponsive, based on the spindump analysis:

WindowServer Deadlock

The spindump data shows that the com.apple.hiservices-xpcservice process is stuck waiting for the WindowServer. This service is responsible for managing graphical operations on macOS. Messages like turnstile waiting for WindowServer indicate that the process is blocked from accessing critical resources, leading to a system deadlock.

Kernel-Level Blocking

Threads within the process are halted, waiting for mach_msg_overwrite and mach_msg2_trap system calls. These indicate that the process is attempting to communicate with other system services, but it remains stuck due to unresponsive system-level communications.

Wake-from-Sleep Issues

The analysis suggests that the issue began after waking from sleep mode, as indicated by the system being unresponsive for a prolonged time (~800 seconds). This points to a failure in re-establishing communication with services like WindowServer upon waking.

Resource Access Problems

There are no clear indications of hardware failures in the spindump, but the process seems to have been stalled while trying to access shared resources, hinting at a possible software conflict or misconfiguration.

Once, you mentioned something like, ‘Turn off all the unnecessary settings in Accessibility.’ You suggested this would prevent the process from becoming unresponsive. Below, I’m sharing with you what HIServices does, according to Apple’s official page, for your information. Additionally, by saying this, you’re essentially claiming that Apple’s own system features are causing a problem, which contradicts your own point.

HIServices.framework

Contains interfaces for accessibility, Internet Config, the pasteboard, the Process Manager, and the Translation Manager. Available in OS X v10.2 and later.

At this time, there is no imperial evidence, as to the cause of this issue.

If you believe this to be a serious enough issue.

Would suggestion the following >>

Start now and open an Apple Support Ticket as they are PAID Apple Employees to deal will these types of issues .

Product Feedback - and make it known to Apple regarding this ongoing issue

Have the computer evaluated by the Professionals who have the Special Hardware Software and Expertise to diagnose the issue and offer possible solutions

Make an Appointment at the Apple Genius Bar or call 1 800 MyApple and have them evaluate the computer

It looks like there’s a misunderstanding. Simply having an app on the App Store does not mean Apple automatically takes a cut. For free apps, like many on the store, Apple doesn’t take any percentage. Apple only charges a fee on paid apps or in-app purchases.

The claim that being on the App Store only means Apple takes a percentage is completely incorrect.

Developers use the App Store for more than just revenue sharing, it offers better security with sandboxing, trusted app distribution, and broader access to users. It’s about providing a secure and convenient experience, not just revenue.

Please don't confuse the users.

What the Third Party Application may do to the computer is up to the User to check this out before purchase.

Download the Application Etrecheck ( External Link ) directly from the Developer.

The Application is Not a " Silver Bullet " and is only a tool to examine the Hardware / Software used on this computer

Ya estoy cansada de este error, siempre aparece y es más repetitivo cuando trabajo en Excel, lo peor, consume una memoria impresionante. 1.70 GB. Sucede mucho *** aplicaciones de Microsoft, como Excel y Adobe Pro que dejan de responder.

This issue seems to relate directly to a Third Party Applications from Microsoft

Not unlike using Microsoft Edge on Apple Computer

Apple can fix Apple Services, Apple Applications, Apple Operating Systems and Accessories

Apple can not fix Third Party Applications

Apple can’t fix the Users’ choice of Third Party Applications installed and use on this computer.

That clearly falls Out-Side of the Domain of Apple and belongs solely with the Third Party Application Developers

In the specific context of the Suppled Report for a M3 MBA 2024

Your machine has 16 GB Unified RAM versus mine 8 GB Unified RAM

You machine has been On for 1 Day versus my about an hour

Battery Count on your is at 61 Full Cycles and mine 6 Full Cycles

I do not see Numbers, Pages, Keynote, GarageBand, iMovie showing as having having been installed, which is Standard installed as a New Computer

The two machines each have the same 500 GB SSD drive

The point being, on my M3 MBA, which is almost identical in most hardware and software configuration

The cursoruiviewservice' Not Responding and Causing Lag on MacBook Air does not occur

Nor does it occur on a M1 and M2 machines

All the machines have been upgraded from every version macOS 14 up to and including Sonoma 14.6.1 and onto macOS 15.0 Sequoia

In good faith. the Etrecheck Report for this machine ( mine ) is listed below for your own comparison and verification

Good Faith

Yes, all these issues began after installing Sonoma. I will update you with Apple Support's response when I receive it this week. Thank you for your help.

This is not normal at all, and interestingly, we're still not getting any response. This issue started with Sonoma, but if you search for "com.apple.hiservices-xpcservice" on search engines, you'll see that this process has been unresponsive for years with no solution found. Strange!!

For those running Apple Silicon M-Class computers

Unlike some other experiencing this >> " Finally, Apple engineers investigated the issue and discovered that it's a software problem affecting M-series processors"

Have a 2020 M1, 2023 M2 and 2024 M3 computers all with Sonoma 14.6.1

Zero issues " ' cursoruiviewservice' Not Responding and Causing Lag "

Not doubt if this issue were present while running Apple Silicon M1, M2, M3 computers, these machines would have been affected by this issue.

Just saying

A bug in the operating system doesn't have to be experienced by allusers. Some issues can only be encountered on certain devices. You might not have seen it before, but update notes often mention that "some users are affected." Th fact that you haven't experienced it doesn't mean the bug doesn't exist. I have a case number and recorded evidence.

Over two months,... the problem still exists.

Respectfully, Sonoma was first released September 26, 2023, almost a full year

If as has been stated early " Finally, Apple engineers investigated the issue and discovered that it's a software problem affecting M-series processors".

That all encompassing statement attributed to Apple Engineers would affect all and not some selective M1, M2 and M3 machines

Still not having this issue

Hi PRP_53,

As far as I can see, the process is using 10.4 MB of RAM on your system, but this issue generally occurs after it reaches 90-100 MB, and some users have reported that this process uses 300-400 MB. From what I understand, you've either been using the computer for a short time or you're restarting it frequently.

On the other hand, the "com.apple.hiservices-xpcservice" process became unresponsive again even though I performed a clean install of macOS 15.0 via USB and no applications were installed.

You keep saying that the issue isn’t on your end, but I don’t exactly understand what you’re trying to say. Are you implying that such an issue can’t exist? If you can’t offer a solution, I don’t think it really matters whether the issue is on your side or not.
