A lot of logs in console related to WindowServer (Long render detected)

I'm seeing a lot of logs with same signature as below, it is around 3 to 10 per second:


WindowServer: (QuartzCore) [com.apple.coreanimation:WindowServer] Long render detected. Swap 13888 took 3.3e+02s


What could be the reason, it is happening even if I don't connect to external display and no application is running. (even tried to kill all background apps)

I found software called "Bambi" as a Private Framework and the only reference online I could find was this:

I found logs in a folder called "CoreTelephonyTraceScratch":

Bambi is a character you will find in the logs.You have nothing to worry about seeing any reference to Bambi. Software Engineers are "funny" people and you will see many names or messages that will not make any sense to you. Some will be related to fictional characters or to the internal codename for the project they are working on. The only person who it does make sense for if the one that told the process to print the message. More Bambi info is here:

And you will even recognize those same logs here:

References to telephony logs are seen with any log related to the communication chip. This is an integrated chip that includes anything from Wifi, Bluetooth, Radio Frequency, and even Cellular. Apple may not use all the features of the chipset even though you will see those logs. For example, the chipsets have also included the ability to receive radio stations with the RF module and Apple does not include the antenna or software to implement that feature, even though you may see a reference to it.


The logs you see are specifically written to print the message you see. You will not find a nefarious process that is going to print a log of what it is doing. They would want to hide their activity on your device and would not be telegraphing this to you. It is not the OS that is warning you of anything that is nefarious, it is the actual process itself that is printing the message because the engineer told it to print that.


The classic log message that has worried users for over 25 years is the famous "Goodnight, Gracie" message you will find. Users were concerned that they had someone logged into their computer name Gracie and there have been many posts about this where they think they have been hacked. It is just another example of the humor engineers used while programming:

Yes that same Enter Old Password is normal including the product name that you see.

I have no idea why your privacy report shows a different Mac than what you have, but would be a good question for Apple. I would suspect you have found a bug with their reporting as apparently it does show the correct SN of your device and Apple should be able to determine product model by its serial number.
