Delete Webpage Preview Fetcher?

So... I'm still trying to get a grasp on these large webpage preview caches. I will never use Top Sites, so it is useless to me.
What if I were to delete the Fetcher from Safari---> Show Package Contents? (I understand I may need to compress it first). What would be the ramifications of such an action? Has anyone else tried this?
I just want these Gigs of useless caches to stop!
Thanks in advance

Hi
That's a good question. I haven't tried it yet. If you feel so inclined, make a copy of Safari.app first (command/D keys), then make the change. Restart Safari and see what happens. If Safari crashes, you got your answer. Move to the trash Safari.app. Then, rename Safari (copy).app to Safari.app and you are back to square 1.

  • How to permanently stop Safari Webpage Preview Fetcher process?

    Since the Safari Webpage Preview Fetcher process takes up to 10% of my CPU on occasion and and it uses bandwidth and it's just dumping loads of images into ~/Library/Caches/com.apple.safari/Webpage Previews is there a way to permanently stop this process from ever starting up again?
    I've blocked it with Little Snitch to see if it that stops it but I don't think it has. Has anyone successfully stopped this process for the long term?

    i'd like to permanently stop that as well.

  • Runaway PubSubAgent & Safari Webpage Preview Fetcher

    Hi-- I'm on 10.6.2 still (well, again, because 10.6.3 killed my Pro Tools system), and PubSubAgent regularly starts to runaway with ~97% of my processor. I kill it with Activity Monitor & all's well again for a while, until it decides it's the most important thing on my computer again a few hours later.
    I gather this is a part of Mail, related to RSS feeds? Does anyone have a suggestion for how I can calm it down?
    I also get this same problem with the Safari Webpage Preview Fetcher sometimes, though less often.
    thanks

  • Safari webpage preview fetcher high CPU usage, runs hot Macbook Pro, fan

    Even when turned off in Safari Preferences, safari webpage preview fetcher starts up and starts using high CPU % (99.8% when checked on Activity Monitor!). Macbook starts running hot, fan starts running on high. You can force quit safari webpage preview fetcher in Activity Monitor, but it starts itself back up again!

    Well, I disabled safari webpage preview in preferences, and rebooted, zapping the pram and it hasn't restarted, and I haven't had the high fan / hot running so yay!

  • Safari 4 "Webpage Preview Fetcher" runaway process

    I just installed the new Safari 4 via Software Update Utility. Process called "Safari Webpage Preview Fetcher" is chewing up 50 - 75% of my CPU and isn't stopping. I've tried restarting Safari with no luck. Safari is basically unusable - I'm writing this from Firefox.
    Any ideas?

    I found this on a board and tried it. Works great with no resulting glitches (so far).
    1. Quit Safari 4.0 and right-click on it's icon in the Finder. Select "Show Package Contents".
    2. Look inside the Contents folder and right-click on Safari Webpage Preview Fetcher and select Compress "Safari Webpage Preview Fetcher".
    3. Put the original Safari Webpage Preview Fetcher in the trash and empty it.
    4. Navigate to ~/Library/Caches/com.apple.Safari/Webpage Previews and highlight it. Get Info on it.
    5. At the bottom click on the padlock, type in your password and then change the Privilege column for your login name to "Read only" and lock the folder. Close the Get Info window.
    6. Launch Safari.

    HI,
    "preview fetcht" is a process that "fetches" TopSites previews.
    From the Safari Menu Bar, click Safari / Empty Cache. When you are done with that...
    From the Safari Menu Bar, click Safari / Reset Safari. Select the top 5 buttons and click Reset.
    Empty your cache and Reset Safari once a week.

  • Deleting Aperture previews not working as expected

    Hello,
    I am trying to reduce the number of pictures from my Apreture library that show up in the Media Browser. As far as I can tell, I need to tell Aperture to stop automatically generating previews and then I can manage them myself.
    This is what I am doing:
    1. Within Aperture Preferences I have unchecked the box that says "New projects automatically generate previews"
    2. Under the option "Share Previews with iLife and iWork" I have selected "When quitting Aperture"
    3. Under the Library Actions menu (little gear icon in the Library bowser pane on the left) I have unchecked "Maintain Previews For Project" for all of my projects
    4. Under the Photos menu I have selected "Delete Previews for Library"
    5. Quit Aperture
    6. Open Mail app and compose an email. Then try to attach a photo from my Aperture library
    7. Proceed to notice that ALL OF MY APERTURE PICTURES STILL SHOW UP IN THE MEDIA BROWSER!
    This is driving me crazy and I don't know why it's not working. There seem to be a number of users that are successfully managing their previews like this.
    Am I doing something wrong or missing a step?
    Any help is appreciated.

    Hi Frank,
    3. Under the Library Actions menu (little gear icon in the Library bowser pane on the left) I have unchecked "Maintain Previews For Project" for all of my projects
    What did you have selected in the library when you unchecked this?
    I had the particular project that I wanted to exclude selected.
    4. Under the Photos menu I have selected "Delete Previews for Library"
    You selected all your images (or at least the ones you want to delete the previews for) before running this. correct?
    Yes I did.

  • How do I disable the webpage preview that pops up when I hover my mouse over a tab?

    I don't know why this started today, but it is driving me nuts!
    I was surfing the net, when all of a sudden I noticed that whenever I hovered my mouse over one of my tabs, a (poorly rendered) preview of the webpage popped up from my mouse. I really do not need this feature. I don't need to have a mini-webpage preview of another tab.
    Please, how do I disable this feature?
    *note: I have disabled all my add-ons, and still nothing. I disabled my hardware acceleration, and still nothing. Please!

    I've never noticed that. Do these old threads shed any light?

  • Is it safe to delete all PREVIEW files in the FINDER's "All my files"?

    I have > 7,000 files showing in the PREVIEW section of the Finder's ALL MY FILES.  I want to clean up unnecessary and duplicate files - most are photos. I just want to make sure that if I delete these preview files it will not remove the original  file.

    ALL MY FILES is exactly what the name implies — it is a list of all of your files. They are not duplicates (unless you see more than one copy of the same file in the All My Files list). If you delete something from that list, you are deleting the one and only instance of that file.

  • How do you disable WEBPAGE PREVIEW IMAGES in Safari 4?

    Since I checked the 'show webpage preview images' immediately after upgrading, I've been losing hard drive space like there's no tomorrow. Every time I visited a few sites for the first time with Safari 4, I'd lose 10 MBs. After a few days I lost over 200 MBs and had enough of it. So I went to Reset Safari and noticed that now you could 'remove all webpage preview images' without resetting anything else. When I did this, I got all my space back.
    I don't see anyway to undo this feature. Top Sites and Cover Flow like integration with bookmarks are nice if you've got a big screen and hard drive.

    I know this thread is "answered", but I'll chime in.
    I locked the said folder, and it worked fine. However, this error was marked repeatedly, ad infinitum, in the console log, for every single page I visited:
    <Error>: CGImageDestinationCreate destination parameter is nil
    It was getting so out of hand, filling my console.log, I had to unlock the folder.
    Is there a way to lock the webpage preview cache folder, and not have Safari write to the log?
    Thanks

  • Safari 5 doesn't saves webpage preview images

    Safari doesn't saves webpage preview images. It only save images for my Top Sites pages.
    When I look in my history cover flow I only see blank Safari symbols (except history from my Top Sites webpages)
    Well I really want to see full cover flow.
    How can I fix this?
    By the way, the Reader feature really cool and very useful.

    By the way, I finally gets history to be saved. It fixed by Safari 5.
    Yes, I saw your post on that one ... at least some incremental progress is being made ...
    There's an area of Discussions (available only to the level 4 or 5 users) where we can post information about trouble we see out in the "public" forums ("Notable New Technical Issues"). I've been updating a thread on this issue with your progress so far with this. (I'm not sure if the Safari developers watch that though ... but just in case, I've been stashing info about this there.)
    In the meantime, it's probably worth submitting a bug report via the "Help > Report Bugs to Apple" or the Apple Bug Reporter thing (if you've registered as an Apple Developer).

  • I deleted the preview files and now the sequence on the timeline is missing

    I deleted the preview files to save disk space by doing Sequence/ delete render files, now the sequence on the timeline window is missing. what can i do te recover the already assembled sequence on the timeline?
    Help please!!!
    Elio

    First, are you sure that you deleted the Preview files, and not your media files? Can you check in Windows Explorer, that your media files are still where you had them?
    Next, if it was the former, and not the latter, this should not happen. Did PrPro give you any sort of message, when you loaded your Project? Something like "where is file xxxx.AVI?"
    There are instances where Sequence Timelines do not appear in the Timeline Panel. I'd not think that this would be one of those instances, but... is your Sequence still showing in the Project Panel? What happens if you Dbl-click on it there?
    Do start checking the sales for hard drives. Editing video without enough hard drive real estate is asking for problems. It will be money well-spent.
    Good luck,
