After installing mavericks on mac mini network printers disappeared

After installing Mavericks on my Mac Mini, all printers on the home wifi network disappeared and cannot get them back. Tried deleting and re-installing printers and all updates. Network does not see them from the Mac Mini. Is there some workaround or solution to this? Everything worked perfectly until the Mavericks upgrade.

Was there any evidence of a new or update printer driver at the Epson site for use with Mavericks OS X? Even if so, that may not be enough as the peripherial makers can be steps behind a new & different OS.
I have two Epson printers, one is an all-in-one WF845 (bought at 50% off) and an older Photo Stylus 820, this still makes great prints; both work wireless in different ways. However I have what are essentially antiques in both hardware and software.
Not sure if there are any third party drivers that could help as a fix or a patch for the situation you face, if Epson hasn't a working alternative to being printerless. Too bad that paperless society didn't evolve to save a few trees and thousands of gallons in expensive ink.
Good luck & happy computing!

How to install MAVERICKS on Mac Mini 2014

Hi everyone,
I just bought a Mac Mini (late 2014) and I tried to delete yosemite and do a clean install of Mavericks with a pen drive.
Unfortunately when I try to start my Mac mini from the Pen Drive with mavericks installer it gives me a white page with a ACCESS DENIED symbol in the very center.
Is there a particular way to install mavericks on the newest mac mini, I really need to do that cause I'm working with softwares that works only on mavericks for now.
Thanks in advance,
Alessione

Unfortunately, that is only allowed if Mavericks is already installed:
(iii) to install, use and run up to two (2) additional copies or instances of the Apple
Software within virtual operating system environments on each Mac Computer you own
or control that is already running the Apple Software, for purposes of: (a) software
development; (b) testing during software development; (c) using OS X Server; or (d)

After installing Yosemite my mac mini takes forever to do anything

since my recent software update most of the time all i get is the spinning icon due to my mac mini being so slow, all this is used for is a media hub for films.
Can anyone shed some light on this please

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
The title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar at the top of the screen.
Click the Clear Display icon in the toolbar. Then take an action that isn't working the way you expect. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.

MacBook pro late 2011 (4G, i7) very slow to load any program after installing Mavericks

After instaling Mavericks, my Mac has slowed down so much, when I turn on my Mac it takes forever to load, and after it loaded, takes longer (then what it did before) to load any program.
Any help please?
My specs: MacBook PRO 13" late 2011, 4Gb RAM, Intel i7 2.8Ghz System most of the times shows 90-97% on idle (yet slow).

Check activity monitor, if a keener activity is taking a lot of CPU resources then Try this link http://www.rdoxenham.com/?p=259
You will have to keep an eye on your temperature, but that's it.

Hi,
What version of the OS did you upgrade from ?
Anything before OS X 10.8.2 may have an issue if the Logic/Mother board has been replaced and the Serial Number not "flashed" back to it.
In the Apple Icon menu use the About this Mac item.
In the new panel click twice on the line that tells you the current OS level
It will change to the Build number (and alternative count to the OS versions) and then the Serial Number.
If it is missing you need to get it replaced.
(It is supposed to be done on Repair or Refurbishment).
An Apple Store or Apple Authorised Service Provider as the best choices.
There are apps you can download (They are Mac Model specific) but needs careful typing as it is a once only trip.

Hmmmm... would appear that you need to be actually logged in to enable the additional menu features.
Have you tried deletting the plists for MAS?
This page might help you out...
http://www.macobserver.com/tmo/answers/how_to_identify_and_fix_problems_with_the _mac_app_store
Failing that, I will have to throw this back to the forum to see if anyone else can advise further.
Let me know how you get on?
Thanks.

For the fan issue, see if you can reset the SMC > Intel-based Macs: Resetting the System Management Controller (SMC)
That may help the restarts as well.

After installing Mavericks stuck on Setting up Your Mac after restart

After installing Mavericks which was extremely slow a number of software applications also had updates. All of this took more than a day. After that my login was slow but everything worked.
The other user's log in got stuck on Setting up your Mac. Then I made mistake of going in under my own log in and changing start-up to go automatically to the other user automatically. Now I can't log myself in anymore and I am totally hung up now on Setting Up Your Mac without any access.

Welcome to the Support Communities! The article below will help you troubleshoot the issue you are having with starting up your Mac:

Shut it down by holding down the power button for about 10 seconds. Hold down the Option key and start up your computer again. Keep holding down the Option key until one or more disk icons appear on your screen. Select one of the disks. After your computer starts up, choose Apple menu > System Preferences, click Startup Disk, and select a disk.

After installing Mavericks, office for mac 2008 doesn't work properly

After installing mavericks, office for mac 2008 is slow, unresponsive a lot of the time, and slows my whole mac down if i want to do other things at the same time. Is there a solution that doesn't involve spending loads of money on a newer version of office for mac?

All Good. Are there any pending updates for MS Office by chance? Just check under the Help menu in the top Menu when you open Word.
I highly recommend you to reinstall the latest Office 2008 update > http://www.microsoft.com/en-us/download/details.aspx?id=36897 Note that Office 2008 is not supported by Microsoft anymore (thanks Mende1 for the link)

Hi,
You don’t install VS2010 on the client PC, then where did the Form Invoice not work? When you run it from another version of VS? Or when you run the application with application.exe?
Based on your description, one form works well, another form does not. I assume that two forms are in two different projects, then please check the .Net Framework used by the two projects. If they are different, you can use the
one used by the Form contact for Form Invoice.
Because this issue is a project issue, I recommend you to consult it on some application forum such as Windows Forms General forum for better support.
VS General Question forum mainly discusses
the usage of Visual Studio IDE such as
WPF & SL designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help
System and Visual Studio Editor.

Almost. Anti-virus software is completely superfluous for Mac.
I have tested most of the commonly available Mac "anti-virus" products under controlled conditions. The only differences between them are their varying degree of worthlessness. Some are malicious and will corrupt your Mac. The vast majority of Mac problems reported on this site are the direct result of using such products.
OS X already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
A much better question is "how should I protect my Mac":
Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Disable Java in Safari > Preferences > Security.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

After installing Maverick on my macbook pro, imessage on my ipad and Iphone stopped working properly. Is there a fix/test.

After installing Maverick on my macbook pro, imessage on my ipad and Iphone stopped working properly.
What I get is a RED exclamation and "Not Delivered". It happens even if i resend it over and over.
I have made sure that the 3 devices all have the same settins in iMessage.
I have made sure to try doing it from the same network and from the cell provider network.
I have tried rebooting all three devices.
The only way to get it to work on my iphone and iPad is to dissable it in Mavericks on my MacBook Pro.
Is this a "feature" of the new OS?

Hi,
On the iOS devices remove the Apple ID.
Set the device in to Airplane Mode (this breaks with the server)
Start with the iPhone to add back the Apple ID - only after you see the iPhone Number is Verified.
The Restart the Mac Version
Accept the pops ups that state what the iPhone is using.
Do same on iPad.

IMac 24" doesn't start after installing Mavericks.

After installing Mavericks (10.9.2) the machine started having hiccups... rebooting at random times on it's own. After upgrading to 10.9.3, it only got worse. Reboots were more frequent (as little as 1 minute between each reboot). Then it took the final step and went into a state where it remains with black screen, the startup jingle may begin, but is killed within half a second or less... goes into a reboot loop. The DVD sounds, then it tries to reboot again, DVD sounds... sometimes the jingle starts... but is cut off by a reboot. Trying to get ANYTHING done with different key press combinations (option+command+R+P, D, T, Command, Option... pretty much every single combination one can find online for accessing safe boot or recovery or whatever... does not work. The machine seems to have been killed by Mavericks. I have come across a LOT of posts by other people who have experienced the same thing (rebooting after installing Mavericks) going back to October last year, and a few have experienced the same dead computer issue as I am having... all the while there is no fix or explanation from APPLE regarding this issue. I have even opened the machine up and checked all cable connections, tested the HDD on another computer (was ok), cleaned the memory module connectors etc. Before the total crash I had installed a temperature monitoring program with ventilator control, due to the DVD ventilator running at high RPM after installing Maverics. All the temp sensors were reporting modest temps (ranging from 39 - 79 Celsius (only the power supply was above 50 Celsius).
The computer is as useful as a brick by this point. Since it went dead, it has successfully started up 3 times (out of 500+ attempts), but rebooted within a couple of minutes, into it's cycle of dead reboots.
One way of getting it to boot and prepare for re-installation, is to keep the power button pressed until it sounds 3 times long, 3 times short and 3 times long beeps... it would only start making the first beep... then it rebooted in to death again.
Could it be that Mavericks is destroying the firmware, or even killing the hardware? I also have Mavericks on MBA and MBP, where the MBA has no problems, while the MBP freezes up every 2 days or so... requiring a forced reboot.
Anyone with a usable advice on what to do in order to get the machine working again? How many years does it normally take APPLE support staff to fix serious issues like this one? It's already been over 7 months since the first people began experiencing these issues with Mavericks, but nothing has been done about it on APPLE's end ... as far as I can tell.
Looking forward to some solutions.

Just wanted to write the conclusion of this issue here, and make things as clear as possible.
I took the iMac to a support center, and they confirmed that several components on the power supply board were fried and other parts had been overheated. It took a few weeks for them to get the needed parts (much cheaper than replacing the entire unit). I brought the iMac back home and started it up, and it did work... but it was getting very hot very quickly. I was thinking that maybe I should install Mountain Lion on it, and get away from Mavericks... just in case.... the computer had been turned on for around 1 hour at that point, and then it rebooted.... and stayed dead for 10 minutes or so... until it could start up again. Was on for a few minutes... then dead again.
Clearly the cause of the problem was still present, and fixing the symptom did not prove to be a lasting solution.
The machine would not stay turned on long enough (when it DID turn on) for even formatting the disk, so I removed the SDD from it, formatted it with my MBA (connected through USB), and inserted it in the iMac again. Starting it up resulted in a few minutes being turned on, overheating and crashing. Having downloaded ML and created a USB installer for it, it was now a case of trying one's patience ... hoping for the machine to stay turned on long enough to make it all the way through the installation process.... it managed to do the first part of the installation after several hours of crashing and overheating.... and it came to a point where I simply turned it off and gave up... thinking that the problem simply was physical in nature, and not caused by Mavericks as I had assumed from the start. Next day I had renewed energy, turned the puter on and it behaved in the same way... turning off, then starting by itself trying to get through the installation.... it would fail again and again... I left the house, with it turned on, hoping that it would at least manage to finish at some point in time... so that I could write off my "BAD Mavericks" suspicion. When I returned several hours later, the installation was complete and the machine was purring quietly and the back of the computer was NOT hot like a steam iron.
Now it has been working for several days without any problems at all.
The final conclusion is this:
Mavericks IS at fault, and will physically DESTROY computers that are "somehow" not compatible with it. I would have thought that Apple had enough capable engineers to prevent the operating system to mess up the hardware in this way, but clearly I was wrong on that account. I can only WARN other people to even attempt installing Mavericks on puters of this type:
Hardware Overview:
Model Name:   iMac
Model Identifier:     iMac7,1
Processor Name:       Intel Core 2 Duo
Processor Speed:      2.4 GHz
Number of Processors: 1
Total Number of Cores:        2
L2 Cache:     4 MB
Memory:       4 GB
Bus Speed:    800 MHz
Boot ROM Version:     IM71.007A.B03
SMC Version (system): 1.21f4
Serial Number (system):       W8*******X89
Hardware UUID:        00000000-0000-1000-8000-001B639688F7
Anyone claiming that Mavericks is not at fault, is plain and simple WRONG, in DENIAL or LYING. There is absolutely NO doubt in my mind any longer, that the problem was indeed Mavericks getting installed on the machine and messing with the hardware on a level where it should never happen. If someone working at Apple would like to purchase/replace my iMac in order to test it and figure out that this is a REAL problem, they are welcome to do so. I think it is more than guaranteed that the damage caused by this Mavericks nightmare installation will never be recovered, nor will the time and work lost ever be compensated, but I would actually like Apple to acknowledge their responsibility and failure to address this issue in a professional and responsible way.
IF Mavericks was NOT at fault, then someone should explain the logic behind the machine physically burning components shortly after the installation of Mavericks, and even when the SDD had been wiped clean with no OS, it was still overheating and shutting off, until it could finally have ML installed... and at that point it was cured and has worked flawlessly ever since. Not a single hiccup, no over heating, no problems.
My offer to sell/replace the iMac stands if Apple is really interested in looking at this SERIOUS issue with Mavericks. This is NOT a minor issue they should expect simply goes away, or will be ignored by people who experience their machines BURNING to pieces.
On my MBA and MBP Mavericks is not causing any problems, so it is not "all bad", but for the iMac it meant total annihilation.
Anyone who has installed Mavericks on their iMac of similar age as mine, having rebooting and overheating problems: REMOVE the Mavericks installation ASAP and get ML on it before it goes up in flames!
Other Mac's have been reported having the rebooting/overheating problems as well, although I have not noted down which builds those were. The problem is REAL and COSTLY for those who experience it.... both time-wise and in terms of lost time/work.
Hopefully this will help others from getting the same terrible experience as I got, and save some computers from burning up.

Hello M.A.S.Ramos,
Thank you for using Apple Support Communities.
For more information, take a look at:
OS X Mavericks: Wirelessly mirror your Mac screen to your HDTV
http://support.apple.com/kb/PH14375
Make sure your Mac and your Apple TV are on the same network.
Choose your Apple TV from the AirPlay status icon in the menu bar.
Choose This Mac or your Apple TV depending on how you want to match the desktop size of your Mac.
OS X automatically detects an Apple TV when it’s on the same network, and displays the AirPlay icon in the menu bar. When AirPlay Mirroring is active, the status icon is blue.
Have a nice day,
Mario
