OSX Yosemite Wifi FIX!!

I found a way to fix the wifi issue on my iMac which i upgraded from maverick to Yosemite OSX. I got fed up with all the fixes that didn't fix the problem so I opened app store and re-downloaded Mavericks.. I noticed that for two hours my wifi didn't drop once. then within 2 minutes after download it disconnected...... So after a thought, i opened my torrent program and let 1 file seed at .2K and magically no wifi issue as long as something is always using the connection....

Try the workaround suggested in this article: http://tidbits.com/article/15273?rss

OSX Yosemite wifi issues

Running:
Model Name: MacBook Air
Model Identifier: MacBookAir6,2
Processor Name: Intel Core i7
Processor Speed: 1.7 GHz
Yosemite 10.10.1 (14B25)
The constant wifi problems from switching locations and having the wifi drop are causing major issues. I have to shutdown wifi then restart ever time I change locations in my office.
If I move more than 10 ft. (switching wifi hubs) my wifi will look like its working but I actually get no connectivity.
Since this has been months since the

This is SOO annoying. Mavericks had its issues with JUMBO Frames that was never fixed but this is crazy now. Last night I upgraded to Yosemite from Mavericks. Now I can see my 5Ghz SSID but only have internet for 30 seconds at best. I don't even see my 2.4GHz network at all. If I toggle Wifi on and off I see the 2.4 for a moment and then gone. I removed all favorite wifi's and manually configured the 2.4 and will not connect. Removed that one and tried 5Ghz and same 30 seconds. I have done all updates, I have restarted numerous times and no go!
I did a fresh (clean) install. I formatted the HDD and had the original Lion install by default that came with the unit. It booted, had internet fine and then upgraded straight to Yosemite and immediately no wifi. Can anyone say if they did a clean install but from Mavericks and upgraded to Yosemite with same results??
What kills me is that apple doesn't seem to be giving ANY information out, no acknowledgement, and certainly no fix yet. I feel more and more like I am purchasing Microsoft Products where I am beta testing. If apple knew in Beta releases this was an issue with ALOT of people, they should not have released this yet! My laptop is my business and I am now tethered to a cable for everything!
Bluetooth disabled made no difference for me. Also I found that if I disable wifi while using my ethernet it will disconnect connectivity from ethernet until I unplug and replug...
APPLE ??? I guess I should just make some apple juice? or can I get some lemons??

OSX Yosemite wifi connection issues

Hello,
i have a MacBook Pro (late 2011) with OS X 10.10.3.
I use the MacBook in a office enviroment in a WPA2-Enterprise WiFi with authentication over a Free-Radius server.
Every 30 minutes to one hour my connection to the wifi drops, sometimes it reconnects immediately and I only realize i got a disconnect because a download stopped but sometimes it can't reconnect for a couple of minutes.
I tried the obvious solution like restarting the MacBook and deleting the WiFi profile.
Currently my investigation focus on the AP we use in our company (D-Link DWL-8600AP). I tried using a spare Router and I was able to keep my connection to the WiFi.
The Question I have is is it possible that the Access Point has problems with Macs or if it is another one of the Mac WiFi problems.

Hello there, 39Steve.

Wifi problem with OSX Yosemite

I owned my first 13 inch MBP Late 2011 that came with OSX Lion. I upgraded my MBP with every new OSX releases and were very pleased with them.
With OSX Yosemite, I was very happy with the fresh new feel and looks of it. The problem with the new OSX it that my wifi connection suffers from it. The speed are getting slower and slower and the connection often drop off unexpectedly. The worst thing of all is that I can't connect to my windows phone wifi sharing. This doesn't happen with the previous OSXes. Please rectify this problem as soon as possible. Thank you.

Any other troubleshooting steps for Yosemite WIFI issues?

I've spent several hours this weekend at my friend's house trying to fix the WIFI issues on her Macbook. I had installed some software on it recently (Chrome, Plex, Teamviewer) and I removed all of it just in case there was a conflict (Plex being the only thing I could think might be causing an issue with the Plex server running.) I then realized she had upgraded to Yosemite and found out there seems to be a lot of WIFI issues going on. I've come across several blogs with troubleshooting steps and here is what I've tried so far:
-Reset the modem to factory settings
-Toggled the checkbox to authenticate changes in networks
-Renewed DHCP lease
-Disabled Bluetooh
-Removed network configuration and preference files (and later restored the backups I had of them)
-Created a new WIFI location with a custom DNS
-Unloaded/reloaded discoveryd files
I wasn't able to get any kind of WIFI connection between removing the network configuration and preference files and unloading / reloading the discoveryd files but then I plugged into the ethernet after reading there were some conflicts with Apple applications so I re-installed Chrome and the WIFI started working again for a little bit. I am typing this from my Macbook still running Mavericks on the same WIFI connection so I'm fairly sure this incident in 99% Yosemite and nothing else on the computer. I'm willing to try any other intermediate troubleshooting. She needs her computer a lot this week (works from home and has a big event this weekend) so I am going to hold off on the fresh OSX Yosemite install or an attempt to downgrade to Mavericks again - fingers crossed the update is out before that becomes a necessity.
Thanks for reading!

Slow internet speed with OSX Yosemite

I updated to OSX Yosemite & now my internet speed is painfully slow on my Mac book Pro 15 Retina. It work fine (Great), prior to the update. Is there a known problem and fix for this?

Yosemite created two problems for me and the problems happened immediately, I never had any internet connection problems with Mavericks OSX.
Problem 1) My internet speed went from 85MPS to 35MPS. This happened on both of my MacBook Pro Laptops with Yosemite. Using the same router with a non-Yosemite computer yields 85MPS or greater speeds.
Problem 2) WiFI connection looks normal but internet connections don't work. Pinging APPLE.com though the terminal yields the same result, No Response. I used the ping command to rule out a Safari problem. Normally one of my laptops will not go online at all. *** To work around problem 2, I am using Two Routers. If one doesn't connect or drops, I simply use the other one. Both Yosemite MacBooks drop my internet connections constantly, regardless of which router I use, but I have notice that the faster Comcast router drops more frequently. Sometimes when I connect to the COMCAST router I cannot get any internet data (Safari or Ping). This is very repeatable and is intermittent.
Apple please advise me what to do!!!! I use VPN's and work through the internet. This is affecting my job performance.
Thanks

Is there a way to disable mouse acceleration in OSX Yosemite?

i have used my dads iMac and MBP in the past and always noticed how bad the mouse response was in my opinion. Mind you, some people like the way the mouse responds in OSX and will probably have no idea what my issue is. That is mouse acceleration and the lack of option to disable it in the mouse settings panel. Here is a good explanation about what it is, also in the video is a visual example.
"Mouse or cursor acceleration, to put it simply, makes the travel distance of your cursor on the screen reliant of the velocity of your physical mouse movement rather than just the distance that you move your mouse. So making one movement of the same distance at two different speeds will cause two different relative cursor movements, with quick movement causing the cursor to travel a greater distance."
source:
https://www.youtube.com/watch?v=16diwK6HWbI
So the thing i want to accomplish, is making the physical mouse movement one-to-one with the cursor speed on the screen. As an example: moving my mouse 10 cm would always make my mouse on the screen go 1000 pixels, no matter how fast i move my mouse.
I've had my mouse set up like that in windows and linux for quite some time now and i hope there is an easy way to set the mouse response like that in OSX as well.
I want to make clear that this isn't just an issue in games where you want to have great mouse precision. I have become really accustomed to this way of mouse response in any type of application. So the problem lies not in any mouse settings of any game/program. The problem lies in how OSX translates physical mouse movement to cursor movement.
Anyway, i ran into this issue about a year ago when i was using my dad's computer. i've had my own windows computer for some time now. An option to disable mouse acceleration in OSX Yosemite might have been implemented properly in the mean time. I have searched this community and found some old posts of people who had this same problem as me, but never read about any fix for it. The main reason i am asking this is because i am considering buying a Macbook.
I'd rather not use any third party software, but if there is any out that that just works and is easy to use, let me know.

Please don't be obnoxious to people like tbirdvet trying to help; nobody here owes you an answer, or anything else for that matter.
Anyway, Yosemite seems to enable mouse acceleration by default. You can disable it to get a constant pixels pointer moves / meters mouse moved ratio by typing this in terminal:
defaults write .GlobalPreferences com.apple.mouse.scaling -1
you'll need to logout and log back in for changes to take effect. To restore the standard behaviour:
defaults write .GlobalPreferences com.apple.mouse.scaling 2
should do the trick.

Can't upgrade Macbook Pro to OSX Yosemite

Hi - I've been trying to update my MacBook Pro Mid 2009 to OSX Yosemite. After dowloading and running the installer, it goes through the process of preparing the installation, closing all programs and preparing to restart. Then I get this error.
I've tried:
-Running the application again
-Redownloading the Yosemite software multiple times
-Checking for updates
-Running the Yosemite installer with wifi off
-Repairing disk permissions to the hard drive
-Verifying the hard drive disk
-Installing a new version of Mavericks
Any ideas?

Perhaps the HDD does not have sufficient room. It needs a minimum of 5 GB for Snow Leopard.
In all other respects your MBP should be able to install 10.6.
Disk MC223Z/A is the appropriate retail disk.

OSX Yosemite RIM Album Art Deamon crashes every few seconds.

Since my upgrade to OSX Yosemite (OSX v 10.10) the RIM Album Art Deamon chrashes. When I first start up it takes about 2-3 minutes before the first crash, then when I dismiss the crash report, it's only a few seconds until the next one appears.
BBDM was installed prior to the update to Yosemite (It was installed originally on Snow Leopard, but the upgrade was from Mavericksk (OSX 10.9))
I unistalled BBDM, restarted the computer, and there were no crashes, but of course I can't backup my Torch or Playbook. So I re-downloaded BBDM and reinstalled, which required a restart. After 2-3 minutes, a crash, then same behaviour as before.
Any suggestions would be appreciated, as I've updated both of my Macs to the latest software. (BBDM was only installed on one).
Thanks,
Paul

Solved!

I see a lot of BB Link problems out there for Yosemite users. Since Maverick, Sync Services have been removed but there is a workaround. You can sync Music and media still but for Contacts and iCal transfer and updating Blackberry already have a solution. See below.
Sync features that accompany iCloud and Apple ID accounts utilize IMAP, CalDAV, and CardDAV. These accounts can be integrated on the BlackBerry 10 OS.
To integrate an iCloud account that uses an iCloud.com email address:
From the home screen, swipe down from the top bezel and select Settings > Accounts > Add Account > Email, Calendar and Contacts.
Enter the @icloud.com email address and select Next.
Enter the @icloud.com email password and click Next.
Enable the items to be synchronized (Email, Contacts Calendar).
Select Done.
If iCloud is used for synchronization but an @icloud.com email address is not used, or is not enabled, calendar and contact sync can still be integrated on BlackBerry 10 OS and BlackBerry PlayBook OS, however to integrate these, advanced integration steps need to be used instead of the above steps. The email address associated with the Apple ID must be used. To integrate this method, use the steps below.
Note: If either an @me.com or @mac.com email address are being used, integrate as an @icloud.com address (i.e. Instead of using [email protected], use [email protected]). Apple has aliased @me.com and @mac.com email addresses so they will still receive emails, but any outgoing email will appear as the @icloud.com domain.
To integrate an iCloud account that does not use an iCloud.com email address follow the below steps to:
Integrate iCloud contacts using CardDAV:
From the home screen, swipe down from the top bezel and select Settings > Accounts > Add Account > Advanced > CardDAV.
Enter Description (for example: iCloud or the iCloud.com email address).
Enter Username as the either the Apple ID or iCloud.com email address.
Enter Email Address as either the Apple ID or iCloud.com email address .
Enter Password as the Apple ID password.
Enter Server Address as contacts.icloud.com
Select desired Sync Interval from the drop-down menu.
Select Done.
Integrate iCloud calendar using CalDAV:
From the home screen, swipe down from the top bezel and select Settings > Accounts > Add Account > Advanced > CalDAV.
Enter Description (for example: iCloud or the iCloud.com email address).
Enter Username as either the Apple ID or iCloud.com email address.
Enter Email Address as either the Apple ID or iCloud.com email address .
Enter Password as the Apple ID password .
Enter Server Address as caldav.icloud.com or p03-caldav.icloud.com (If an error returns showing the device couldn't connect to p0#-caldav.icloud.com return to the Caldav setup screen and change the server name to reflect the unique number representing the # symbol. This number could be 1-9 depending on what the return message is. Example: p05-caldav.icloud.com or p04-caldav.icloud.com)
Select desired Sync Interval from the drop-down menu.
Select Done.
Integrate iCloud Email using IMAP:
From the home screen, swipe down from the top bezel and select Settings > Accounts > Add Account > Advanced > IMAP.
Enter Description (for example: iCloud or the iCloud.com email address).
Enter Display Name as the name that sent email will display from (for example: Justin Jones)
Enter Username as the iCloud.com or @me.com email address email address.
Enter Email Address as the iCloud.com or @me.com email address email address.
Enter Password as the Apple ID password .
Enter Server Address as imap.mail.me.com
Enter Port as 993
Under Encryption drop-down menu select SSL.
Enter SMTP Username as the iCloud.com or @me.com email address.
Enter SMTP Server Address as smtp.mail.me.com
Enter SMTP Port as 587
Select desired Sync Interval and Initial Retrieval Amount from the drop-down menus.
Select Done.
Note: If the iCloud Email account does not integrate using the above settings, complete the steps again, but under the SMTP Encryption drop-down list select Start TLS.

There seem to be two related issues to the 5th one.

I am using osx yosemite,Do i need antivirus in my pc?

i am using osx yosemite,Do i need antivirus in my pc?

Mac users often ask whether they should install "anti-virus" software. The answer usually given on ASC is "no." The answer is right, but it may give the wrong impression that there is no threat from what are loosely called "viruses." There is a threat, and you need to educate yourself about it.
1. This is a comment on what you should—and should not—do to protect yourself from malicious software ("malware") that circulates on the Internet and gets onto a computer as an unintended consequence of the user's actions. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the computer, or who has been able to take control of it remotely. That threat is in a different category, and there's no easy way to defend against it.
The comment is long because the issue is complex. The key points are in sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user. Internally Apple calls it "XProtect."
The malware recognition database used by XProtect is automatically updated; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
☞ It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
☞ It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
☞ It can easily be disabled or overridden by the user.
☞ A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
☞ An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
Apple has so far failed to revoke the codesigning certificates of some known abusers, thereby diluting the value of Gatekeeper and the Developer ID program. These failures don't involve App Store products, however.
For the reasons given, App Store products, and—to a lesser extent—other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandbox security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. The built-in security features of OS X reduce the risk of malware attack, but they are not, and never will be, complete protection. Malware is a problem of human behavior, not machine behavior, and no technological fix alone is going to solve it. Trusting software to protect you will only make you more vulnerable.
The best defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and Internet criminals. If you're better informed than they think you are, you'll win. That means, in practice, that you always stay within a safe harbor of computing practices. How do you know when you're leaving the safe harbor? Below are some warning signs of danger.
Software from an untrustworthy source
☞ Software with a corporate brand, such as Adobe Flash Player, doesn't come directly from the developer’s website. Do not trust an alert from any website to update Flash, or your browser, or any other software. A genuine alert that Flash is outdated and blocked is shown on this support page. Follow the instructions on the support page in that case. Otherwise, assume that the alert is fake and someone is trying to scam you into installing malware. If you see such alerts on more than one website, ask for instructions.
☞ Software of any kind is distributed via BitTorrent, or Usenet, or on a website that also distributes pirated music or movies.
☞ Rogue websites such as Softonic, Soft32, and CNET Download distribute free applications that have been packaged in a superfluous "installer."
☞ The software is advertised by means of spam or intrusive web ads. Any ad, on any site, that includes a direct link to a download should be ignored.
Software that is plainly illegal or does something illegal
☞ High-priced commercial software such as Photoshop is "cracked" or "free."
☞ An application helps you to infringe copyright, for instance by circumventing the copy protection on commercial software, or saving streamed media for reuse without permission. All "YouTube downloaders" are in this category, though not all are necessarily malicious.
Conditional or unsolicited offers from strangers
☞ A telephone caller or a web page tells you that you have a “virus” and offers to help you remove it. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
☞ A web site offers free content such as video or music, but to use it you must install a “codec,” “plug-in,” "player," "downloader," "extractor," or “certificate” that comes from that same site, or an unknown one.
☞ You win a prize in a contest you never entered.
☞ Someone on a message board such as this one is eager to help you, but only if you download an application of his choosing.
☞ A "FREE WI-FI !!!" network advertises itself in a public place such as an airport, but is not provided by the management.
☞ Anything online that you would expect to pay for is "free."
Unexpected events
☞ A file is downloaded automatically when you visit a web page, with no other action on your part. Delete any such file without opening it.
☞ You open what you think is a document and get an alert that it's "an application downloaded from the Internet." Click Cancel and delete the file. Even if you don't get the alert, you should still delete any file that isn't what you expected it to be.
☞ An application does something you don't expect, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
☞ Software is attached to email that you didn't request, even if it comes (or seems to come) from someone you trust.
I don't say that leaving the safe harbor just once will necessarily result in disaster, but making a habit of it will weaken your defenses against malware attack. Any of the above scenarios should, at the very least, make you uncomfortable.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it—not JavaScript—in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a padlock icon in the address bar when visiting a secure site.
Stay within the safe harbor, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
7. Never install any commercial "anti-virus" (AV) or "Internet security" products for the Mac, as they are all worse than useless. If you need to be able to detect Windows malware in your files, use one of the free security apps in the Mac App Store—nothing else.
Why shouldn't you use commercial AV products?
☞ To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. This technique is a proven failure, as a major AV software vendor has admitted. Most attacks are "zero-day"—that is, previously unknown. Recognition-based AV does not defend against such attacks, and the enterprise IT industry is coming to the realization that traditional AV software is worthless.
☞ Its design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere. In order to meet that nonexistent threat, commercial AV software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
☞ By modifying the operating system, the software may also create weaknesses that could be exploited by malware attackers.
☞ Most importantly, a false sense of security is dangerous.
8. An AV product from the App Store, such as "ClamXav," has the same drawback as the commercial suites of being always out of date, but it does not inject low-level code into the operating system. That doesn't mean it's entirely harmless. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An AV app is not needed, and cannot be relied upon, for protection against OS X malware. It's useful, if at all, only for detecting Windows malware, and even for that use it's not really effective, because new Windows malware is emerging much faster than OS X malware.
Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else. A malicious attachment in email is usually easy to recognize by the name alone. An actual example:
London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe
You don't need software to tell you that's a Windows trojan. Software may be able to tell you which trojan it is, but who cares? In practice, there's no reason to use recognition software unless an organizational policy requires it. Windows malware is so widespread that you should assume it's in every email attachment until proven otherwise. Nevertheless, ClamXav or a similar product from the App Store may serve a purpose if it satisfies an ill-informed network administrator who says you must run some kind of AV application. It's free and it won't handicap the system.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have all the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user, you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither can you assume that you will always be safe from exploitation, no matter what you do. Navigating the Internet is like walking the streets of a big city. It can be as safe or as dangerous as you choose to make it. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

Autocad 2015 Crashing on OSX Yosemite

I recently upgraded to Apple's new opperating system (OSX Yosemite) and am experiencing random crashes every 5-10 minutes on Autocad 2015 for Mac. The crashes are not associated with any specific command or action but rather the program spontaneously quits even when I'm not actually working on a drawing.
According to statements by Autodesk Reps, the crashes are unrelated to the actual software but are rather a result of a driver issue with Intel HD 3000 graphics card's on Apple's end. The following is a link to the original thread on Autodesk's forums:
http://forums.autodesk.com/t5/autocad-for-mac-general/autocad-2015-for-mac-with- os-x-yosemite-crash/m-p/5366839#M13230
My question is if this is in fact the case and whether or not Apple has rectified the issue.
Many users rely on AutoCAD for their professional careers and businesses, thus a fix or at least a statement of reassurance should be made public immediately as right now this is a major inconvenience.
Thanks

[28/01/15 15:59:25] Help And Support: Can you please check for existence of file "com.adobe.PDFAdminSettings.plist" at the following locations:
1. /Library/Preferences/
2. ~/Library/Preferences/
This file might be already present on your machine if you have any other version of Acrobat installed. You need to rename this file or move it to some other location and then try installing Acrobat 11 again. Please let us know if you are able to install after following these steps.
It’s only there in /Library/Preferences
I deleted com.adobe.PDFAdminSettings.plist from /Library/Preferences/ with admin privileges
still the installation fails
Any other suggestions.
I also tried installing with an Admin account, still fails!
