Calendar will not hold window size on restart

By the way: It would help if the mouse pointer turned into an arrow EVERY TIME and not sometimes.

dnapolitano4is correct, but there's a bit more...

1. Click on the "Calendars" button to close the sidebar.
2. Size the window as you prefer.
3. Restart your Mac.
4. Open Calendar app.
5. Click on the "Calendars" button to open the sidebar.

You can, now, safely resize your Calendar with the sidebar open and it will save the window size and the open/closed sidebar.

Warning: Rant Ahead - proceed with caution.

The one thing I hate about any app is being forced to hunt through Google to find the answers to an apps basic functions. It's as if Graphic User Interface design has been left to the programers and CEOs. Seriously, what in Apple's "Photos" app logo has anything to do with photos? AND they killed "Aperture"? All they had to do was buy teorex.com(awesome free apps - PS "content aware fill" isn't this good or easy) and add its functionality and extremely simple GUI to common photo editing hassles. Were all of the graphics designers at Apple fired?

I'll take skeuomorphism over obscure meaningless designs any day. Icons are suppose to make life easier, not a starting point for a morning of Google searching. I like the added whimsy in my work day.

Tiny text in tons of white space is a bizarre MS Windows design decision. My bank did it, too; tiny generic rectangles of a solid color as icons in separate locations on the screen. Why did Apple follow such a lame idea? I had to use numerous System Accessibility settings for my parents and myself just to make the OS X less of a hassle to use. I'm unemployed, can I get a job at Apple making MS-Windows-like icons with rectangles in Playskool colors?

I won't even get started on iTunes insane scrambling, shrinking and changing common icon images (often hiding) it's various functions and menu settings. They are beginning to get into "you must roll your pointer over every pixel to make the function become visible". Go ahead, play a song then resize the window to make a mini-player in the corner of your screen. If you've never stumbled over it, it's faster if you Google the solution than try to find it.

The king has died, the magic is gone, and Camelot has become just another crumbling ancient castle on a tourist Google (not Apple) map; a tale we can tell our grandchildren of a land with magical devices, nearly mind-reading user interfaces, with spectacular announcements and major technology advancements. They once had beautiful stores, filled with industry-leading products, it was like stepping into the future, manned by knowledgeable experts, artists and technicians, no appointment needed, free bottles of cold water if you had to wait.

Our children won't believe us.

Sorry, did not work.

You are correct, and you have my apologies.

After a few days, it reverted to its shrunken size, side bar or not.

Apple support remains silent (no surprise).

So, what's it like being an unwitting beta tester for a company that thinks their new software version doesn't have any major issues and too arrogant to reply?

"Misery loves company" is a poor customer service philosophy.

Apple has moved from excellent to being the lesser of 2 evils.

The king has died; the magic is gone.

Do not apologise ! I appreaciate the intent to help! Just didn't work is all :-)

Software is allowed to be a little buggy at first, but the third version of a release should indeed not display such errors.....

I tried hiding the side bar yesterday and, so far, it works for me on both of my computers.

From what I'm reading, it's only a temporary fix?

If/when the problem returns, I will post here.

Thanks.

It didn't work for me either. I'm still looking for a solution.

Strangely, the window retains the correct width but not the correct height. I tried stretching the window to different widths, and the application always "remembered" the correct width, but the height was always truncated, no matter what I did.

A fix that appears to be holding:

1. Restart while holding the two keys, command + r.
   This will boot into an external "repair" boot screen.
   From here you can fix your boot files.
2. Select "Disk Repair".
3. Select your boot partition (not just the drive).
4. Select "First Aid". This may take awhile.
5. Restart your Mac as usual.

No guarantees: It's El Capitan.

Side note: From what I can tell, based on my past weeks of wrestling with El Capitan as if it were MS Windows, El Capitan alters many diverse files to the point of being nearly useless if the alternate option (MS Windows) wasn't worse. It's similar to a 2 party government; one you dislike and the other you hate; neither improves your life as much as they have deluded themselves into believing. You know it's getting bad when your pocket calculator and note pad are looking like better alternatives.

About a week later, my boot drive itself would not work (boots with a "Do Not Enter" symbol because it can't find it, then powers down). Thankfully, I had a "Time Machine" drive (these days on a Mac, it is VITAL - my 2tb external drive saved my life more than once). I used +r to repartition my boot HD and reinstall the most recent known good moment (about 1 hr before the last one). It took many hours, but everything was returned; emails settings, everything. Alas, my FaceTime still doesn't work after a fresh reinstall of El Capitan, a fixed boot, deleted all FaceTime and message pfiles and their hidden packages/bundles.

If you don't have an iPhone, iCloud is the devil because it deletes all you cherish, including Calendar appointments and doctor numbers, after it transfers it to an Apple server. Your data is gone off of your computer until you reconnect your internet or run to the public library and log into your iCloud externally.

For me, the quest continues, but with one less El Capitan headache. But, the week's not over.

I'm going to stick to the simplest work-around, which is to hide the side bar. I never used it anyway.

My side bar has been kept hidden since January 7th, and Calendar is opening to the size I set it to every time on both of my Macs.

What I wrote doesn't work; the squished calendar came back after a few days. The only solution that others have noted, is to just keep the side bar hidden.

Apparently, I'm putting more effort into making a quality product than Apple does now. Whatever knowledge I have accrued after 25 years in Apple computers and 30 as an electronics engineer is incapable of fighting off the current Slytherin-like influences on Apple's original magic. Most apps have hidden functions that elude me and need Goole searching to find or fix; the apps' "Help" menu is anything but comprehensive help. Other apps still refuse to work at all, such as FaceTime and Messages, all video and text messaging is nonexistent on my Mac after all of the reloads and reboots, including spending the day repartitioning my boot drive and reinstalling a fresh OS. Alas, nothing.

Apple is losing the war because they're underestimated how badly they are weakening their own warriors. Many don't complain, we just walk quietly off the battle field. If Apple isn't going to support me in their own fight why should I continue to fight to make them better? I don't know of a single friend with a Mac (there are many) that hasn't thrown their hands up in a tired disgust at an app made by Apple. They call on me to "come fix my Mac, it...", but I'm tired and have no new magic for them. I was the one that turned most of them away from MS Windows and onto Mac. I feel I have failed. The new Apple Slytherin System is too powerful. Their UI, User Interface has been contorted into User Interference. I can only surmise there are superficial self-interests of evil forces at work in the heart of the castle.

To my fellow warriors, sorry.

You have no idea how right you are. But you have to understand that Windows is still so much worse....

In general, most people, MOST people do just enough. Work just hard enough not to get fired. Apple is no different. In 100 employees maybe 1 or 2 want to do great. But, those people are not alwasy in the position to do great things! Maybe it is the janitor. Important person, but not directly involved in creation and production. Or perhaps they want to do things well, but thaty have no talent. Eager to perform but no great ideas.

You see, that way, even a big company can only have a handful of people that are but driven AND talented AND at the right position AND have great ideas....

I found a solution palliative
Open calendar.app> go to menu View > Hide list of calendars
Close and reopen app.

If you read this entire thread, you will see that others (including myself) have already stated your solution.

Thanks.

I'm having the same issue on one of many Macs. Hiding the tab works in the mean time.

Dealing with Apple support became so unpleasant these days I would like to avoid it if possible.

Usually it takes three calls alone to find someone who is understanding what the problem really is.

I hope Apple to fix this without having to moan around with them.

Whew, I thought I was going crazy. CoreForce, I'm glad you replied. I just saw it happen again.

The "solution" people are claiming, is NOT a valid solution.

To prevent your Calendar from shrinking, you must never have your Calendar's sidebar open when you close the app then restart your Mac.

I did what people have mentioned and it does NOT solve the problem. They want you to add Calendar as one more updated and "improved" Apple app that you must tolerate its new flaws, its degradation in quality.

I could, perhaps, join the minions of Apple worshipers. I once was one. But, those were times when Apple earned their users' respect with incredibly advanced software, when UI = User Interface not UI = User Interference. I loved telling my MS Windows-using friends that my Mac does everything with half as many mouse clicks. Today, I have friends that refuse to update their OS X and its older apps because there is nothing to replace it or it is vastly different and more difficult and complicated to use.

I agree, the reduction in Apple's app quality could be made more tolerable if they had a support staff that were knowledgeable and caring. I worked in a support call center... twice. When they tacked a call handle countdown timer to the wall and made tech support must also handle tracking packages so they can reduce the number and quality in both departments, there was a palatable feel to the company's slow death. They keep adding layers of cheap, brightly colored frosting to a cake that is rotting in the middle; confusing "impressive" with "important".
