Why won't my hp scanner and fax work after (upgrading) to Yosemite?

Why is the Yosemite slowing down my computer? I can't get anything to download and I can't get my scanner to work! This has been so frustrating since upgrading?!

MacBook Pro (13-inch Mid 2009), Mac OS X (10.5.8)

An upgrade to a later operating system, especially of such a wide gap in years,

from OS X 10.5.8? to OS X 10.10, would usually be limited on an older Mac...


The amount of installed chip RAM (memory) should be increased as part of

a hardware upgrade prior to attempting to upgrade to a much later OS X.


Usually an older computer, even if it's said to be capable to Yosemite, would be

marginal since early model Intel-Mac are not quite up to the later standard for

the newest system; and older Macs are limited in hardware upgrade capabilities.


If your computer's hard disk drive, has a rather full percentage of saved content

and older applications, that too would contribute to a much slower experience.

A lack of resources will make any OS X run slow. There is more to an upgrade

than to simply install a later OS X; the hardware should also see an upgrade.


There are many details missing in your initial post, and that lack of info isn't helpful.


Good luck & happy computing! 🙂

The MacBook Pro model you've stated can be upgraded to more RAM

as indicated by information from http://mactracker.ca database, here:


Maximum Memory 8.0 GB

Memory Slots 2 - 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM

If the above matches this other information then you should have no

trouble acquiring quality RAM from vendors such as Crucial.com or

macsales.com (OWC) and be sure to avoid bargain-based RAM as

those kinds of low-end products are less stable & can fail under load.

Information for MacBook Pro (13-inch, Mid 2009) -- to compare specs:


Introduced June 2009

Discontinued April 2010

Model Identifier MacBookPro5,5

Model Number A1278

EMC 2326

Order Number MB990LL/A (2.26 GHz), MB991LL/A (2.53 GHz)


The upgrade of memory chips (RAM) of the correct specification & of

quality reputable brand, is not too difficult; note your MB/Pro in Link.


You may be able to upgrade the internal hard disk drive to greater

capacity, note there is a helpful link to iFixit repair guides; however

it would be best to use a second computer whilst upgrading the first

or have someone who is familiar with the specific model you have

on a technical basis. A different kind of upgrade may include an SSD.

Hopefully you can resolve this issue, however you may need to contact

an Apple Genius at official Apple Store (set appointment ahead of visit)

or a specialist AASP authorized service expert, if you need tech help.


Some independent sales/service providers may specialize in older Macs

and could provide upgrade service on old models no longer seen by an

official Apple Store. The independent shops may do upgrades, etc.

There are some upgrades you or a capable friend, could do yourself.


A genius/specialist could help by inspection/testing, and may suggest

ways of making it work better. As it is getting older, could be a new HDD

& some RAM, may be sufficient and less costly than a new MacBook.


In any event...

Good luck & happy computing! 🙂

A question:


Do you (also) have a Mac Mini as well as the MacBook Pro mentioned in your post?

If so, please specify, since your topic appears in Mini ASC topic area & not MB/Pro.


A reply (added in regard to MacBook Pro, not Mini) with more information about that

model and not MINI, does not seem to be visible when I visit this thread. So perhaps

it may appear if this one sticks... That was added yesterday w/ MacBook info links.


Hopefully you can resolve the issues, perhaps visit an Apple store genius or see

what an authorized Apple service provider could do for your MacBook or ? Mac.


A post of the suggested Etrecheck report, could be give us clues, by the way.


Good luck & happy computing! 🙂
